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