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 5a - 5a = 9a - 2z + 6 for a in terms of z.
| -\(\frac{1}{6}\)z - \(\frac{5}{6}\) | |
| -z + 1 | |
| -3\(\frac{1}{2}\)z + 4 | |
| -\(\frac{3}{4}\)z - 1\(\frac{1}{2}\) |
