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 - 9b = 9b + 2z - 3 for b in terms of z.
| -\(\frac{1}{3}\)z + \(\frac{1}{3}\) | |
| z - 5 | |
| -\(\frac{11}{13}\)z + \(\frac{3}{13}\) | |
| -4\(\frac{1}{3}\)z + 1\(\frac{2}{3}\) |
