solve for the equation.
4x -(3x-1) =2

the answer is 1. but how did they do the equation?

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

-
4x - (3x-1)=2
4x - 3x + 1 = 2
x + 1 - 1 = 2 - 1
x = 1
substitute!
4x - (3x-1) = 2
4(1) - [3(1) - 1] = 2
4 - (3-1) = 2
4 - (2) = 2
4 - 2 = 2

-
4x - (3x-1) = 2

4x - 3x + 1 = 2

1x + 1 = 2

x = 1
