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