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 -3a - 6a = 3a - z + 1 for a in terms of z.
| -1\(\frac{4}{7}\)z - \(\frac{3}{7}\) | |
| z + \(\frac{5}{9}\) | |
| -\(\frac{5}{6}\)z - \(\frac{1}{6}\) | |
| -2\(\frac{1}{5}\)z - 1\(\frac{1}{5}\) |
