1) 3x - 4 = x + 2 2) 1 - 2x + 2x= 6 + x 3)- x + 7 = 3 x - 5 4) 5x= 1 + 4x

1. 1) 3x-4=x+2

Lets put the variables on one side and the numbers on the other side. Every variable or number that will change sides, will have their sign changed from a + into a - and vice versa.

3x-x=2+4

2x=6

Divide both sides with 2.

2x/2 = 6/2

x=3

2)1-2x +2x=6+x

1=6+x

Lets put the variables on one side and the numbers on the other side. Every variable or number that will change sides, will have their sign changed from a + into a - and vice versa.

x=1-6

x=-5

3) - x + 7 = 3 x - 5

Lets put the variables on one side and the numbers on the other side. Every variable or number that will change sides, will have their sign changed from a + into a - and vice versa.

3x+x=7+5

4x=12

Divide both sides with 4.

4x/4 = 12/4

x=3

4) 5x= 1 + 4x

Lets put the variables on one side and the numbers on the other side. Every variable or number that will change sides, will have their sign changed from a + into a - and vice versa.

5x-4x = 1

x=1
