Answer:
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
Best of Luck!
