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 + 6a = -6a + 3z + 7 for a in terms of z.
| -\(\frac{3}{14}\)z + \(\frac{1}{2}\) | |
| \(\frac{4}{11}\)z - \(\frac{9}{11}\) | |
| -1\(\frac{3}{7}\)z + \(\frac{6}{7}\) | |
| -\(\frac{1}{11}\)z + \(\frac{4}{11}\) |
