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