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 c - 4c = 3c + 2x - 7 for c in terms of x.
| -1\(\frac{8}{9}\)x + \(\frac{5}{9}\) | |
| -3x + 3\(\frac{1}{2}\) | |
| -x + \(\frac{4}{15}\) | |
| x + 1 |
