Question

Can someone help me 3y-20=8y

Answer 1

Objective: Solve 3y - 20 = 8y for y.

Step 1: Collect the y-terms.
To collect the y-terms, you'll need to subtract 3y from both sides.

3y - 20 - 3y = 8y - 3y
             -20 = 5y

Step 2: Isolate y.
Now that there is only one variable term, you must isolate the variable by dividing the term by the coefficient of the variable.

-20 ÷ 5 = 5y ÷ 5
        -4 = y

Answer:
y = -4
