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