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 6a + a = 4a + 2x - 3 for a in terms of x.
| \(\frac{1}{2}\)x - 1\(\frac{1}{2}\) | |
| -1\(\frac{2}{3}\)x - \(\frac{1}{9}\) | |
| -\(\frac{6}{13}\)x + \(\frac{4}{13}\) | |
| x + 4\(\frac{1}{2}\) |
