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 - 2a = 3a + 3x + 7 for a in terms of x.
| \(\frac{3}{8}\)x + 1\(\frac{1}{8}\) | |
| 10x - 9 | |
| x - \(\frac{2}{9}\) | |
| -\(\frac{5}{8}\)x - \(\frac{7}{8}\) |
