9 (0.5y + 0.4) = 5 (0.1y+ 1.3) + 0.3 what is y

y = 0.8

Step-by-step explanation:

9(0.5y + 0.4) = 5(0.1y + 1.3) + 0.3

~Distribute both sides

4.5y + 3.6 = 0.5y + 6.5 + 0.3

~Simplify right side

4.5y + 3.6 = 0.5y + 6.8

~Subtract 3.6 to both sides

4.5y = 0.5y + 3.2

~Subtract 0.5y to both sides

4y = 3.2

~Divide 4 to both sides

y = 0.8
