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 -3a + 6a = -4a - 9x - 6 for a in terms of x.
| -\(\frac{3}{8}\)x - \(\frac{1}{8}\) | |
| -2\(\frac{4}{5}\)x + 1\(\frac{4}{5}\) | |
| -5x - 2\(\frac{1}{2}\) | |
| -15x - 6 |
