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 5b - 3b = b - 8z - 4 for b in terms of z.
| -\(\frac{4}{13}\)z - \(\frac{8}{13}\) | |
| -1\(\frac{1}{4}\)z - 1 | |
| z - 2 | |
| -1\(\frac{1}{12}\)z - \(\frac{3}{4}\) |
