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