Answer:
Step-by-step explanation:
Use the distributive property to remove the parentheses. Then use the addition property of equality to move the variables to the left and the constants to the right. Then simplify both sides of equation. Divide -1.76 to both sides of equation to solve for d.
1.8(6.4d + 4) = 1.6(8.3d + 6.7)
11.52d + 7.2 = 13.28d + 10.72
11.52d -13.28d = 10.72 -7.2
-1.76d/-1.76 = 3.52/-1.76
d = -2
