Step-by-step explanation:
Simplifying
2(3x + -4) = 6x + 5
Reorder the terms:
2(-4 + 3x) = 6x + 5
(-4 * 2 + 3x * 2) = 6x + 5
(-8 + 6x) = 6x + 5
Reorder the terms:
-8 + 6x = 5 + 6x
Add '-6x' to each side of the equation.
-8 + 6x + -6x = 5 + 6x + -6x
Combine like terms: 6x + -6x = 0
-8 + 0 = 5 + 6x + -6x
-8 = 5 + 6x + -6x
Combine like terms: 6x + -6x = 0
-8 = 5 + 0
-8 = 5
Solving
-8 = 5
Couldn't find a variable to solve for.
This equation is invalid, the left and right sides are not equal, therefore there is no solution.
