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 -5c + 4c = 7c - 8x - 8 for c in terms of x.
| -\(\frac{6}{7}\)x - \(\frac{3}{7}\) | |
| 5x - 2 | |
| \(\frac{9}{11}\)x + \(\frac{9}{11}\) | |
| x + \(\frac{2}{3}\) |
