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