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 = -5a - 2z + 6 for a in terms of z.
| -4z + 3\(\frac{1}{2}\) | |
| -\(\frac{7}{8}\)z + \(\frac{3}{4}\) | |
| -\(\frac{1}{3}\)z + 2\(\frac{1}{3}\) | |
| -\(\frac{7}{10}\)z - \(\frac{3}{10}\) |
