can u solve the equation

1)1.2x= 2.3x-2.2

2)[x-4]= 15

3)[13+2x]= 5

1) 1.2x = 2.3x - 2.2
2.2 = 2.3x - 1.2x
2.2 = 1.1x
x = 2

2) x - 4 = 15
x = 15 + 4
x = 19

3) 13 + 2x = 5
2x = 5 - 13
2x = -8
x = -8/2
x = -4

it's all about getting the same variables to the same side of the equation. put the x's on one side of the equation(doesn't matter which side) and the numbers on the other side. then you can solve easily.
