Answers
1) Add the whole numbers first ( 7 and 2 )
9+7/8+11/12
2) Find the Least Common Denominator (LCD) of
7 / 8,11 / 12
Start by Listing Multiples
List out all multiples of each denominator, and find the first common one.
8 : 8,16,24
12 : 12,24
Therefore, the LCD is 24
Method 2: By Prime Factors
List all prime factors of each denominator, and find the union of these primes.
8 : 2,2,2
12 : 2,2,3
Therefore, the LCD is 2×2×2×3=24
3) Make the denominators the same as the LCD
9+7×3 / 8×3+11×2 / 12×2
4) Simplify. Denominators are now the same
9+21 / 24+22 / 24
5) Join the denominators
9+21+22 / 24
6) Simplify
9+43 / 24
7) Convert 43 / 24 to mixed fraction
9+1 19 / 24
8) Simplify
10 19 / 24

y/7 = 4
To get rid of the denominator of y, we have to multiply both sides by this amount (7).
(y/7)*(7) = (4)(7)
When we simplify, we get:
y = 28
If we go back to the original equation and plug in our answer, 28/7 = 4, we can see that it results in a true statement.
Therefore, the answer is y=28.
To isolate y, we need to multiply either sides by 7 to cancel out the fraction.
7 and 7 cancels out
y = 28

3x - 2y = 8
please show work and the solution to the system for x, y
I have tried and tried can't seem to get it to work out.
Answers
3x - 2y = 8 this is the same as 3x/2-8/2=y, which gives you; y=1,5x-4
so;y=23-3xy=1,5x-4
y=y
23-3x=1,5x-4
23+4=1,5x+3x
27=4,5x
27/4,5=x
x=6
the y is:
3*6+y=23
18+y=23
y=23-18
y=5
1) 3x +y=23 try to label them one and two.
2)3x -2y=8 First lets find the x. To do that we have to changed the y,and find the common number fo them.
---------------------------------
1) 3x+y=23 try to times the whole equation number 1) by 4, and equation 2) by 2.
2) 3x-2y=8
----------------------------------------------
1) 12x+4y=92 That's how the euation should look after you would times it.
2) 6x-4y=16 Then add them.
---------------------------------
12x +6x = 18x ..... 4y+4y_ this won't have to be solved at we only had to times it so we could eliminate does y's as we only wanted to find out x.
92+16=108
---------------------------------------------
So then we have...
18x = 108 This means we have to divide 108 by 18 to find out x.
108/18 = 6.
x=6.
-------------------------------------------------------------------------------------------------------------------
To find y we have to do the same method but we have to eliminate x, by findin a common number in x's.
1) 3x+y=23 Try to time the two equations by 2.
2)3x-2y=8
-----------------------------------------------
1) 6x+2y=46 Yoou should get something like that. Then add them.
2) 6x-4y=16
---------------------------------------------
6x+6x_ we won't gonna add them as we only had to multiply them to get the same answer to eliminate these.
2y+ -4y= -2y ............. 46+16=62
-------------------------------------------------------------------
So it should be: 2y=62
---------------------------------------------------------------
No we only have to divide 62 by 2, which is 31
so y=31.
