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 - 3a = 6a + 8x - 2 for a in terms of x.
| 11x - 2 | |
| 1\(\frac{2}{7}\)x - \(\frac{2}{7}\) | |
| \(\frac{5}{7}\)x - \(\frac{3}{7}\) | |
| x + 1 |
