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