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 2a - 7a = -4a - 8x - 2 for a in terms of x.
| -5\(\frac{1}{2}\)x - 4\(\frac{1}{2}\) | |
| -4\(\frac{1}{3}\)x + 3 | |
| -\(\frac{1}{6}\)x - \(\frac{1}{3}\) | |
| -\(\frac{1}{9}\)x + \(\frac{8}{9}\) |
