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