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 = -4a - 3z - 6 for a in terms of z.
| -\(\frac{1}{16}\)z + \(\frac{1}{8}\) | |
| z + 1\(\frac{2}{7}\) | |
| -9z - 6 | |
| -3\(\frac{1}{2}\)z + 4\(\frac{1}{2}\) |
