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 - 9a = -7a + x + 5 for a in terms of x.
| -\(\frac{1}{2}\)x + \(\frac{1}{4}\) | |
| \(\frac{4}{15}\)x + \(\frac{3}{5}\) | |
| 1\(\frac{4}{7}\)x - 1 | |
| -10x - 5 |
