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