Solve an equation

7y – 6y + 12 = 4y

Simplify 7y – 6y + 12 = 4y

7y – 6y + 12 = 4y becomes

y + 12 = 4y when we combine like terms

Collect Get variables together

y + 12 = 4y since there are fewer y’s on the left I move the single y on the left by subtracting y

y – y + 12 = 4y – y which becomes

12 = 3y

Isolate and Solve

12 = 3ythe variable is already isolated so all we have left to do is solve – divide by whatever is with the y

12 = 3y3 3

This becomes

4 = y
