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 3c - 7c = -7c - 2x + 5 for c in terms of x.
| 3x + 1\(\frac{1}{2}\) | |
| -15x - 8 | |
| -15x + 2 | |
| \(\frac{1}{2}\)x + \(\frac{1}{2}\) |
