Question

What value of w makes the equation true? Please explain:

-10w + 12= -9w +13

Answer 1

w= −1

Explanation:

Let's solve your equation step-by-step.

−10w+12=−9w+13

Step 1: Add 9w to both sides.

−10w+12+9w=−9w+13+9w

−w+12=13

Step 2: Subtract 12 from both sides.

−w+12−12=13−12

−w=1

Step 3: Divide both sides by -1.

−w/-1 = 1/-1

w= −1
