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 -2a - a = 4a + 4x - 7 for a in terms of x.
| -\(\frac{5}{6}\)x + 1\(\frac{1}{6}\) | |
| \(\frac{11}{13}\)x + \(\frac{6}{13}\) | |
| -1\(\frac{5}{6}\)x - 1\(\frac{1}{6}\) | |
| -2\(\frac{1}{8}\)x - \(\frac{3}{8}\) |
