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 + 6a = 8a - 5z + 6 for a in terms of z.
| -1\(\frac{2}{3}\)z + 1\(\frac{1}{3}\) | |
| -\(\frac{7}{16}\)z - \(\frac{3}{16}\) | |
| \(\frac{11}{14}\)z - \(\frac{3}{7}\) | |
| 1\(\frac{1}{10}\)z - \(\frac{1}{10}\) |
