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 -4a + 6a = -5a + z + 3 for a in terms of z.
| \(\frac{1}{13}\)z + \(\frac{9}{13}\) | |
| \(\frac{12}{17}\)z + \(\frac{1}{17}\) | |
| \(\frac{1}{13}\)z - \(\frac{2}{13}\) | |
| -5z + 3 |
