Multi-Step Equations
Solve:
2(4-d+2d) = 12

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

  • Math 8 - help!!!!!!!!!!!!!!! -

    2(4-d+2d) = 12

    8 - 2d + 4d = 12

    2d = 12 - 8

    2d = 4

    d = 2

  • Math 8 - help!!!!!!!!!!!!!!! -

    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 .
