Question

how to solve 12x-2(4x-7)=42. Would like to see step process! Please! :)

Answer 1

disitribute -2 to 4x - 7 first

Answer 2

so it would be 12x-8x+14=42 ?

Answer 3

yeah then simplify

Answer 4

Thank you soo much! :) Would you happen to know how to figure out 4[2-(2x-3)]=2(8-3x)

Answer 5

yeah

Answer 6

first work whatever is in the innermost part

Answer 7

-(2x-3) is simply -1(2x-3)
distribute or it's a matter of change in signs

Answer 8

so 4[-4x+6]=16-6x ?

Answer 9

2-2x+3

Answer 10

then it becomes
4(2-2x+3) or 4(-2x-1)

Answer 11

you are not distributing the 2 on the left hand side of the equation, there is a minus sign after the 2 so it is a subtraction operation not multiplication

Answer 12

okay.
