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