5y-14=2y-2 solve for y and show work plz
MrMuchimi

Answer:

y=4

Step-by-step explanation:

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

5y−14=2y−2

Step 1: Subtract 2y from both sides.

5y−14−2y=2y−2−2y

3y−14=−2

Step 2: Add 14 to both sides.

3y−14+14=−2+14

3y=12

Step 3: Divide both sides by 3.

3y/3=12/3

y=4
