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 + 8a = 6a - 2z - 3 for a in terms of z.
| -5\(\frac{1}{2}\)z + 4\(\frac{1}{2}\) | |
| 2z - \(\frac{1}{3}\) | |
| -6\(\frac{1}{2}\)z - 4\(\frac{1}{2}\) | |
| \(\frac{5}{6}\)z + \(\frac{1}{4}\) |
