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 8a - 8a = 3a - 7x + 2 for a in terms of x.
| -\(\frac{1}{5}\)x - \(\frac{4}{5}\) | |
| x - \(\frac{5}{12}\) | |
| 1\(\frac{8}{9}\)x + \(\frac{8}{9}\) | |
| \(\frac{1}{5}\)x + \(\frac{2}{5}\) |
