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 - 6a = -8a - x + 5 for a in terms of x.
| \(\frac{1}{7}\)x + \(\frac{3}{14}\) | |
| 3x - 3\(\frac{1}{2}\) | |
| x + 2 | |
| \(\frac{1}{3}\)x + \(\frac{1}{3}\) |
