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