Question

Solve for varible
-7y=91
a/9=-4
-1/2m=-9

Answer 1

y = -13

a = -36

m = 18

Explanation:

-7y=91

divide both sides by -7

-7y/-7 = 91/-7

y = -13

a/9=-4

multiply both sides by 9

9(a/9) = 9(-4)

a = -36

-1/2m=-9

multiply both sides by 2

2(-1/2m) = 2(-9)

-1m = -18

divide both sides by -1

m = 18

Answer 2

1. y= -13
2. a= -36
3. m= -18
