Multi-Step Equations

Question

Solve:
2(4-d+2d) = 12

please help me!!!! I'm struggling in this question a lot!

Answer 1

2(4-d+2d) = 12

8 - 2d + 4d = 12

2d = 12 - 8

2d = 4

d = 2

Answer 2

First multiply the 2 on the left hand side with each item in the brackets.

2*4 - 2*d + 2*2d = 12
8 - 2d + 4d = 12

Now add all the similar terms on left hand side. i.e 2d & 4d

8+4d = 12 now subtract 8 from both sides
8-8+4d = 12-8
4d = 4
d = 1

If I helped you then reply and Thank me or appreciate it .
