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 + 4c = -4c + 6x - 7 for c in terms of x.
| -13x - 3 | |
| \(\frac{3}{17}\)x - \(\frac{2}{17}\) | |
| 7x - 1 | |
| x - 3\(\frac{1}{2}\) |
