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 -7a + 7a = -5a - 8x - 7 for a in terms of x.
| -2\(\frac{1}{6}\)x - \(\frac{5}{6}\) | |
| 7\(\frac{1}{2}\)x + 3\(\frac{1}{2}\) | |
| 12x + 9 | |
| -1\(\frac{2}{9}\)x - \(\frac{2}{3}\) |
