Question

Y/4+−49=−9

Answer 1

Remember you can do anything to an equation as long as you do it to both sides

(y/4)-49=-9
isolate the variable
add 49 to both sides
y/4=40
multiply both sides by 4 to clear fraction
y=160

Answer 2

So,

$\frac{y}{4}+\ -49=-9$

$\frac{y}{4}-49=-9$

Add 49 to both sides.

$\frac{y}{4}=40$

Multiply both sides by 4.
y = 160

Check.

160/4 + -49 = -9
40 - 49 = -9
-9 = -9

This checks.

S = {160}
