Explanation:
First thing you need to do is simplify the expression by combining like terms:
2 + 2 - 4 + 8d = 4
4 - 4 + 8d = 4
0 + 8d = 4
8d = 4
Next step is you need to try to isolate the unknown on one side of the equation.
To do this, you transpose or you divide both sides of the equation by 8, to keep the equation true:
We simplify the fraction:
If you want to check, just substitute the value of d.
2 + 2 - 4 + 8(1/2) = 4
0 + 4 = 4
4 = 4
