What is the value of x in the equation 2x + 3y = 36 when y = 6
Answers
2x+3*6=36
next you multiply 3*6 to start simplifying for x:
2x+18=36
after that you need to isolate the variable x by using inverse operations(subtract 18 from both sides:
2x+18-18=36-18
simplify that:
2x=18
do inverse operations again this time you need to use division:
2x/2=18/2
simplify for your answer:
x=9

Answer: 2(z - 12) = 63
Step-by-step explanation:
Our task is to write the following:
- twice the difference of z and 12 equals 63
So first, the difference of z and 12 means we're subtracting z and 12, and it's written this way:
Next, twice that difference is: . The reason why we need to put parentheses is because that way, 2 is multiplied by both z and -12.
This equals 63:
Answer:
2(z - 12) = 63
Step-by-step explanation:
Twice --> 2*
Difference of z and 12 --> (z-12)
Equals 63 --> = 63
If you combine...
2*(z-12) = 63
You can remove the * sign, because there is a bracket next.
2(z - 12) = 63

Answer:
4/5
Step-by-step explanation:
{(2/5) / (1/2)} ×1
= (2/5)÷(1/2)
= 2/5×2/1
= 4/5
Answer:
4/5
Step-by-step explanation:
Because if it can eat 2/5's in 1/2 hours, then if it eats for 1 whole hour or 2/2's it will be able to eat 4/5's of it's own body weight.
Just imagine that one half hour is 1 and if you add two half hours together it makes one complete hour or 2/2. So just multiply it by 2 cause it was eating for two half hours.
2x + y = 7
3x + 5y = 14
Answers
You have the equations...
2x+y=7
and
3x+5y=14
To be able to even solve for any of the variables...multiply the equations by...2...and..3...
2x+y=7----*3--> 6x+3y=21
and
3x+5y=14-----*2--->6x+10y=28
Thus,
6x+3y=21
-
6x+10y=28
=========
-7y=-7
y=1
Now, plug y back into any of the original equations....we'll use 2x+y=7 in this case....
2x+(1)=7
2x+1=7
-1 -1
2x=6
x=3
Thus, the point of intersection for these two equations is (3,1)
