Answer: d=91
Explanation:
First thing first, you have to use the distributive property. Distribute the 8 to the d-87.
(8*d) - (8*87) = 32 = 8d - 696= 32
Next, you have to add 696 to both sides of the equation:
8d-696 +696= 32+696 = 8d= 728
Last step is to divide both sides by 8:
8d/8 = 728/8 =
d= 91
We can check this by plugging the number 91 to the variable d in the equation:
(8*91) - (8 *87) = 32 = 728 - 696= 32
