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 8a - 3a = -5a + 2z + 5 for a in terms of z.
| \(\frac{5}{13}\)z + \(\frac{5}{13}\) | |
| -1\(\frac{3}{14}\)z + \(\frac{3}{14}\) | |
| -1\(\frac{1}{14}\)z + \(\frac{5}{14}\) | |
| \(\frac{1}{3}\)z - 1 |
