Question

Linear equations:
-1=5(x-4)-(x-7)
What is the solution set?
How do I solve this,or is it unsolvable?

Answer 1

Simplify the right side of your equation first. Then tell me what you get.

Answer 2

Idl how to simplify it! That's the problem :(

Answer 3

*idk

Answer 4

open the brackets up

Answer 5

@lilg132 , why not add one to both sides and set each bracket = to zero?

Answer 6

How do I combine the two Xs together?

Answer 7

-1 = 5(x-4)-(x-7)

-1 = 5x - 20 - x + 7

now simplify this

-1 = 5x - x -20 + 7

-1 = 4x - 13

-1 + 13 = 4x

12 = 4x

4x = 12

Answer 8

@AmTran_Bus just the way i do it

Answer 9

So the solution set would be 3?
