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 + a = -7a + 4x - 1 for a in terms of x.
| \(\frac{7}{8}\)x - \(\frac{1}{2}\) | |
| \(\frac{5}{11}\)x - \(\frac{9}{11}\) | |
| -\(\frac{1}{2}\)x - \(\frac{3}{8}\) | |
| \(\frac{3}{14}\)x - \(\frac{1}{14}\) |
