Solving Equations by Combining Like Terms

1) The document shows the steps to solve an equation by combining like terms: 7x – 2x^2 – 5x – 4 + 6x^2 + 7. 2) The first step is to place like terms together, resulting in -2x^2 + 6x^2 + 7x - 5x - 4 + 7. 3) The second step is to add and subtract the like terms, resulting in the simplified equation 4x^2 + 2x + 3.
