2.simplify it and find the value of variable
-x-2=6x-12
6x+x=12-2
7x=10
x=10/7
-x-2=6x-12
6x+x=12-2
7x=10
x=10/7
-(x + 2) = 2(3x - 6)
-(x) - (2) = 2(3x) - 2(6)
-x - 2 = 6x - 12
+ x + x
-2 = 7x - 12
+ 12 + 12
10 = 7x
7 7
1³/₇ = x
-5(-4x + 3) = 20x - 6 - 9
-5(-4x) - 5(3) = 20x - 15
20x - 15 = 20x - 15
- 20x - 20x
-15 = -15
-(x) - (2) = 2(3x) - 2(6)
-x - 2 = 6x - 12
+ x + x
-2 = 7x - 12
+ 12 + 12
10 = 7x
7 7
1³/₇ = x
-5(-4x + 3) = 20x - 6 - 9
-5(-4x) - 5(3) = 20x - 15
20x - 15 = 20x - 15
- 20x - 20x
-15 = -15
