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