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 - 2c = -4c + x + 7 for c in terms of x.
| -\(\frac{1}{7}\)x - \(\frac{5}{7}\) | |
| -\(\frac{1}{7}\)x - \(\frac{1}{7}\) | |
| \(\frac{3}{11}\)x + \(\frac{8}{11}\) | |
| x + 2\(\frac{1}{3}\) |
