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 - c = 7c - 7x + 1 for c in terms of x.
| \(\frac{3}{5}\)x - \(\frac{1}{10}\) | |
| -\(\frac{3}{7}\)x + 1 | |
| -\(\frac{1}{13}\)x - \(\frac{6}{13}\) | |
| x - 3 |
