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 -6c - 7c = 6c + 8x - 4 for c in terms of x.
| -6x - 8 | |
| \(\frac{1}{5}\)x + \(\frac{3}{5}\) | |
| -1\(\frac{1}{4}\)x + \(\frac{1}{3}\) | |
| -1\(\frac{2}{3}\)x + \(\frac{1}{6}\) |
