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 5a - 8a = a - 8x + 2 for a in terms of x.
| 1\(\frac{1}{3}\)x - \(\frac{1}{9}\) | |
| 1\(\frac{1}{11}\)x - \(\frac{7}{11}\) | |
| -15x + 6 | |
| x + \(\frac{1}{2}\) |
