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 -4b + 8b = 9b + 4z - 2 for b in terms of z.
| z + 4 | |
| -\(\frac{1}{11}\)z + \(\frac{3}{11}\) | |
| z + 1 | |
| \(\frac{4}{13}\)z + \(\frac{2}{13}\) |
