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 -a - 2a = 3a - 4z - 6 for a in terms of z.
| \(\frac{1}{2}\)z + 1\(\frac{1}{2}\) | |
| -\(\frac{8}{11}\)z - \(\frac{8}{11}\) | |
| \(\frac{1}{5}\)z + \(\frac{3}{5}\) | |
| -\(\frac{11}{16}\)z + \(\frac{7}{16}\) |
