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 + 7c = 3c + 9x + 4 for c in terms of x.
| -\(\frac{2}{11}\)x - \(\frac{4}{11}\) | |
| -3\(\frac{1}{2}\)x + 1\(\frac{1}{2}\) | |
| 1\(\frac{1}{9}\)x - \(\frac{1}{9}\) | |
| -\(\frac{3}{4}\)x - \(\frac{3}{4}\) |
