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