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