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 + 4a = 4a - 6z + 7 for a in terms of z.
| z - \(\frac{7}{10}\) | |
| \(\frac{3}{14}\)z + \(\frac{1}{14}\) | |
| 5z + 5 | |
| -\(\frac{6}{11}\)z - \(\frac{4}{11}\) |
