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 = -7c + x - 3 for c in terms of x.
| \(\frac{8}{15}\)x - \(\frac{1}{5}\) | |
| 15x - 9 | |
| -14x - 5 | |
| \(\frac{4}{13}\)x - \(\frac{8}{13}\) |
