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

Solution for -(1-2r)=-3r+4(r-1) equation:

Simplifying
-1(1 + -2r) = -3r + 4(r + -1)
(1 * -1 + -2r * -1) = -3r + 4(r + -1)
(-1 + 2r) = -3r + 4(r + -1)

Reorder the terms:
-1 + 2r = -3r + 4(-1 + r)
-1 + 2r = -3r + (-1 * 4 + r * 4)
-1 + 2r = -3r + (-4 + 4r)

Reorder the terms:
-1 + 2r = -4 + -3r + 4r

Combine like terms: -3r + 4r = 1r
-1 + 2r = -4 + 1r

Solving
-1 + 2r = -4 + 1r

Solving for variable 'r'.

Move all terms containing r to the left, all other terms to the right.

Add '-1r' to each side of the equation.
-1 + 2r + -1r = -4 + 1r + -1r

Combine like terms: 2r + -1r = 1r
-1 + 1r = -4 + 1r + -1r

Combine like terms: 1r + -1r = 0
-1 + 1r = -4 + 0
-1 + 1r = -4

Add '1' to each side of the equation.
-1 + 1 + 1r = -4 + 1

Combine like terms: -1 + 1 = 0
0 + 1r = -4 + 1
1r = -4 + 1

Combine like terms: -4 + 1 = -3
1r = -3

Divide each side by '1'.
r = -3

Simplifying
r = -3
