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 = 7a + 6z + 8 for a in terms of z.
| 1\(\frac{5}{8}\)z + \(\frac{1}{8}\) | |
| -2\(\frac{3}{4}\)z - 2 | |
| -17z + 3 | |
| -9z + 5 |
