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 -6a - 3a = -5a + 7x - 8 for a in terms of x.
| -10x + 8 | |
| -\(\frac{4}{5}\)x + \(\frac{4}{5}\) | |
| -2\(\frac{1}{5}\)x + 1\(\frac{4}{5}\) | |
| x + 2 |
