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