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