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 -8c + 6c = -9c - x + 7 for c in terms of x.
| -2\(\frac{2}{3}\)x - 1\(\frac{2}{3}\) | |
| -11x - 1 | |
| \(\frac{1}{2}\)x + 3 | |
| -7x + 7 |
