Answer 2

To solve the equation -5(3x+4)+7x=2(5x-16), you'll need to simplify and isolate the variable x. Here's the step-by-step solution:

1. Distribute the constants on both sides of the equation: -5 * 3x - 5 * 4 + 7x = 2 * 5x - 2 * 16

This simplifies to: -15x - 20 + 7x = 10x - 32

2. Combine like terms on both sides of the equation: (-15x + 7x) - 20 = 10x - 32

This further simplifies to: -8x - 20 = 10x - 32

3. Now, let's isolate the variable x by moving the variable terms to one side and the constant terms to the other side of the equation. You can do this by adding 8x to both sides and adding 20 to both sides:

-8x - 8x - 20 + 20 = 10x - 8x - 32 + 20

Simplify: -32 = 2x - 32

4. Next, add 32 to both sides to get the variable term (2x) by itself:

-32 + 32 = 2x - 32 + 32

This simplifies to: 0 = 2x

5. Finally, divide both sides by 2 to solve for x:

0/2 = 2x/2

x = 0

So, the solution to the equation is x = 0.
