When solving an equation with two variables, replace the variables with the values given and then solve the now variable-free equation. (Remember order of operations, PEMDAS, Parentheses, Exponents, Multiplication/Division, Addition/Subtraction.)
Solve -5c + 2c = -9c - 9x - 7 for c in terms of x.
| -5x - 4 | |
| -4x + 1 | |
| -2\(\frac{3}{4}\)x - 1\(\frac{3}{4}\) | |
| -5x + 8 |
