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 - 3a = -8a + 4x - 3 for a in terms of x.
| 8x - 9 | |
| 3\(\frac{1}{2}\)x - 1\(\frac{1}{2}\) | |
| 1\(\frac{3}{5}\)x + \(\frac{9}{10}\) | |
| x + 3 |
