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 a - a = 7a - 6z - 3 for a in terms of z.
| \(\frac{1}{4}\)z - \(\frac{5}{8}\) | |
| \(\frac{5}{6}\)z + \(\frac{1}{2}\) | |
| -\(\frac{9}{11}\)z + \(\frac{8}{11}\) | |
| \(\frac{15}{17}\)z + \(\frac{9}{17}\) |
