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