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 7a - 3a = -7a + 8z - 6 for a in terms of z.
| \(\frac{11}{14}\)z - \(\frac{3}{7}\) | |
| 1\(\frac{6}{11}\)z - \(\frac{6}{11}\) | |
| \(\frac{2}{5}\)z + \(\frac{7}{10}\) | |
| \(\frac{7}{11}\)z + \(\frac{7}{11}\) |
