# How would I solve this equation? watch

1. 2(6 - x) = 3(2x + 2)

I got x = 0.75
2. Expand brackets: 12-2x=6x+6
Solve as usual:
12 = 8x - 6. (Add 2x to each side)
18 = 8x. (Add 6 to each side)
x = 18/8
x = 2.25

3. In my answer book it says -3?

Thanks but in my answer book it says -3 is x? Strange

1. Expand brackets
Gives 12 - 2x = 6x +6

2. Put constants on one side, variables on the other
Gives 6 = 8x

3. Divide by the variable coefficient
Gives x = 0.75.

The book is either wrong or you have misread the question.
5. Sorry you was right I read it wrong I must have been tired last night The question was actually 2(6 - x) = 3(2x + 12)
