Reorder the terms:
1.2 (-5 + 3x) = 1.5 (2.4x + - 4)
(-5 * 1.2 + 3x * 1.2) = 1.5 (2.4x + - 4)
(-6 + 3.6x) = 1.5 (2.4x + - 4)
Reorder the terms:
-6 + 3.6x = 1.5 (-4 + 2.4x)
-6 + 3.6x = (-4 * 1.5 + 2.4x * 1.5)
-6 + 3.6x = (-6 + 3.6x)
Add '6' to each side of the equation.
-6 + 6 + 3.6x = - 6 + 6 + 3.6x
Combine like terms: - 6 + 6 = 0
0 + 3.6x = - 6 + 6 + 3.6x
3.6x = - 6 + 6 + 3.6x
Combine like terms: - 6 + 6 = 0
3.6x = 0 + 3.6x
3.6x = 3.6x
Add '-3.6x' to each side of the equation.
3.6x + - 3.6x = 3.6x + - 3.6x
Combine like terms: 3.6x + - 3.6x = 0.0
0.0 = 3.6x + - 3.6x
Combine like terms: 3.6x + - 3.6x = 0.0
0.0 = 0.0
Solving
0.0 = 0.0
Couldn't find a variable to solve for.
