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 -5c + 7c = -6c + x + 4 for c in terms of x.
| -2x + \(\frac{1}{2}\) | |
| x - 1\(\frac{1}{2}\) | |
| -12x + 7 | |
| -6x + 4 |
