Solution for 2x+1=5x-5 equation
Simplifying
2x + 1 = 5x + - 5
Reorder the terms:
1 + 2x = 5x + - 5
Reorder the terms:
1 + 2x = - 5 + 5x
Solving
1 + 2x = - 5 + 5x
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-5x' to each side of the equation.
1 + 2x + - 5x = - 5 + 5x + - 5x
Combine like terms: 2x + - 5x = - 3x
1 + - 3x = - 5 + 5x + - 5x
Combine like terms: 5x + - 5x = 0
1 + - 3x = - 5 + 0
1 + - 3x = - 5
Add '-1' to each side of the equation.
1 + - 1 + - 3x = - 5 + - 1
Combine like terms: 1 + - 1 = 0
0 + - 3x = - 5 + - 1
-3x = - 5 + - 1
Combine like terms: - 5 + - 1 = - 6
-3x = - 6
Divide each side by '-3'.
x = 2
Simplifying
x = 2
