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 + a = 3a + 3x + 4 for a in terms of x.
| \(\frac{11}{15}\)x - \(\frac{2}{15}\) | |
| -\(\frac{4}{9}\)x - 1 | |
| -\(\frac{2}{7}\)x - 1\(\frac{2}{7}\) | |
| 2x + 4 |
