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 - 5c = -c - 7x - 9 for c in terms of x.
| \(\frac{2}{7}\)x - \(\frac{3}{14}\) | |
| x + 4\(\frac{1}{2}\) | |
| -3x - 5 | |
| \(\frac{3}{4}\)x - 1\(\frac{1}{2}\) |
