1. Start by distributing the 3 to both terms inside the parentheses:
2x - 5 = 3 * 4x + 3 * 5
2x - 5 = 12x + 15
2. Combine like terms on the right side of the equation:
2x - 5 = 12x + 15
-5 - 15 = 12x - 2x
-20 = 10x
3. Divide both sides of the equation by 10 to solve for x:
-20/10 = 10x/10
-2 = x
So the solution to the equation is x = -2.
Use the following step as a guide to solve the following equation. Write out your work for all steps to solve the equation.
2x - 5 = 3(4x + 5)
