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 - 9a = -7a + 5x - 5 for a in terms of x.
| \(\frac{1}{4}\)x - 1\(\frac{1}{2}\) | |
| 3\(\frac{1}{4}\)x - \(\frac{1}{4}\) | |
| 14x - 5 | |
| \(\frac{7}{18}\)x - \(\frac{1}{9}\) |
