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 + 7a = 3a + 4x + 5 for a in terms of x.
| -\(\frac{3}{4}\)x + 1\(\frac{1}{4}\) | |
| \(\frac{1}{12}\)x + \(\frac{5}{12}\) | |
| x - \(\frac{1}{4}\) | |
| 2\(\frac{5}{6}\)x - \(\frac{1}{3}\) |
