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 5a + 3a = 9a + 3x - 9 for a in terms of x.
| 5\(\frac{1}{2}\)x + 1\(\frac{1}{2}\) | |
| x + 2\(\frac{1}{4}\) | |
| -\(\frac{7}{11}\)x - \(\frac{6}{11}\) | |
| 8x + 5 |
