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 a + a = 3a - 5z - 3 for a in terms of z.
| -\(\frac{9}{13}\)z - \(\frac{9}{13}\) | |
| 3z + 1\(\frac{1}{2}\) | |
| 7z - 2 | |
| -\(\frac{2}{3}\)z - 1\(\frac{1}{2}\) |
