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