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 -4c - 3c = c - 4x + 7 for c in terms of x.
| 2\(\frac{1}{2}\)x - 1\(\frac{1}{2}\) | |
| -9\(\frac{1}{2}\)x + 4\(\frac{1}{2}\) | |
| -12x + 7 | |
| \(\frac{1}{5}\)x - 1\(\frac{2}{5}\) |
