Answer:
y = 4
Explanation:
This is a "2-step" equation. Subtract the y-term on the right, then divide by the coefficient of y.
13.7y = 6.2y +30
13.7y -6.2y = 6.2y -6.2y +30 . . . . subtract 6.2y
7.5y = 30 . . . . . simplify
7.5y/7.5 = 30/7.5 . . . . . . divide by 7.5
y = 4 . . . . . . . . . simplify
