Ms. Sue,
2(4d+2d) = 12
8  2d + 4d = 12
2d = 12  8
2d = 4

Math 8  help!!!!!!!!!!!!!!! 
genie_math,
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
88+4d = 128
4d = 4
d = 1
If I helped you then reply and Thank me or appreciate it .
