Answer:
-1 is the answer
Step-by-step explanation:
the question is 3(y-1)=y-5
so, we open the bracets and multiply
so it becomes 3y-3 = y-5
now, we transpose
3y-y =-5+3
2y = -2
y= -2/2 = -1
Answer:
y = -1
Step-by-step explanation:
Hope this helps.
7x + 2y=66
I need a answer in words step by step please help!!
Answer:
x = 10
y = -2
Step-by-step explanation:
Elimination method:
6x - 5y = 70 -----------------(I)
7x + 2y = 66 -----------------(II)
Multiply equation (I) by 2 and equation (II) by 5 and add. So, y will be eliminated and you can now find the value of x
(I)*2 12x - 10y = 140
(II)*5 35x + 10y = 330 {Now add}
47x = 470
x = 470/47
x = 10
Plugin x = 10 in equation (II)
7*10 + 2y = 66
70 + 2y = 66
Subtract 70 from both sides
2y = 66 - 70
2y = -4
Divide both sides by 2
y = -4/2
y = - 2
