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 -a + 5a = -4a - 8x + 8 for a in terms of x.
| 2\(\frac{1}{8}\)x + 1\(\frac{1}{8}\) | |
| -4\(\frac{1}{3}\)x + 2\(\frac{2}{3}\) | |
| -\(\frac{4}{9}\)x - 1 | |
| -\(\frac{1}{7}\)x - \(\frac{3}{7}\) |
