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 4a + 8a = -7a - 2x - 2 for a in terms of x.
| -1\(\frac{7}{8}\)x - \(\frac{3}{8}\) | |
| x + 9 | |
| -\(\frac{10}{11}\)x - \(\frac{2}{11}\) | |
| \(\frac{1}{4}\)x + 1\(\frac{1}{8}\) |
