Answer 1

To solve the equation \( 5(2x+2)−7x=3x+6 \), we first simplify the left side.

1. Distribute the 5: \[ 5 \times 2x + 5 \times 2 - 7x = 3x + 6 \] This simplifies to: \[ 10x + 10 - 7x = 3x + 6 \]

2. Combine like terms on the left side: \[ (10x - 7x) + 10 = 3x + 6 \] This results in: \[ 3x + 10 = 3x + 6 \]

3. Now, let's isolate the terms involving \( x \): \[ 3x + 10 - 3x = 3x + 6 - 3x \] This simplifies to: \[ 10 = 6 \]

Since \( 10 \) does not equal \( 6 \), we have reached a contradiction. This indicates that there are no values of \( x \) that can satisfy the equation.

Thus, the conclusion is:

The equation has no solution.
