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