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 + 9c = -9c + 2x - 5 for c in terms of x.
| -x + 1\(\frac{3}{5}\) | |
| -7x - 5 | |
| -\(\frac{1}{7}\)x - \(\frac{3}{7}\) | |
| x + 8 |
