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 5a - 7a = 4a + x + 5 for a in terms of x.
| \(\frac{3}{7}\)x + 1 | |
| \(\frac{1}{4}\)x - \(\frac{1}{2}\) | |
| 8x + 5 | |
| -\(\frac{11}{12}\)x - \(\frac{3}{4}\) |
