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 2a + 3a = -7a - z - 8 for a in terms of z.
| \(\frac{8}{9}\)z + \(\frac{1}{9}\) | |
| \(\frac{5}{7}\)z + 1 | |
| -\(\frac{4}{9}\)z - \(\frac{8}{9}\) | |
| -\(\frac{1}{2}\)z + 1\(\frac{1}{4}\) |
