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 - 3c = -4c - 3x - 8 for c in terms of x.
| -2\(\frac{3}{4}\)x - 1\(\frac{1}{2}\) | |
| \(\frac{12}{13}\)x + \(\frac{8}{13}\) | |
| -8x - 4 | |
| x - 2\(\frac{2}{3}\) |
