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 - 5a = -8a + x - 1 for a in terms of x.
| \(\frac{1}{6}\)x + \(\frac{1}{3}\) | |
| 1\(\frac{1}{6}\)x + \(\frac{3}{4}\) | |
| 6x - 1 | |
| -\(\frac{3}{5}\)x - \(\frac{3}{5}\) |
