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 - 4a = 7a + 5x - 6 for a in terms of x.
| -\(\frac{3}{5}\)x - \(\frac{3}{5}\) | |
| -\(\frac{9}{14}\)x + \(\frac{3}{7}\) | |
| -16x - 2 | |
| \(\frac{5}{8}\)x + \(\frac{3}{8}\) |
