solve for y.\n9 = 7y + 8(-18 - 2y)\ny =

Explanation:

Step1: Expand the right - hand side

$$9 = 7y+8\times(-18)+8\times(-2y)$$ $$9 = 7y - 144-16y$$

Step2: Combine like terms

$$9=(7y - 16y)-144$$ $$9=-9y - 144$$

Step3: Isolate the term with (y)

Add (144) to both sides: $$9 + 144=-9y-144 + 144$$ $$153=-9y$$

Step4: Solve for (y)

Divide both sides by (-9): $$y=\frac{153}{-9}$$ $$y=-17$$

Answer:

(-17)
