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 -8b + 9b = 3b - 8z - 1 for b in terms of z.
| 1\(\frac{6}{11}\)z + \(\frac{1}{11}\) | |
| 5z - 1\(\frac{1}{2}\) | |
| z - 1 | |
| \(\frac{3}{5}\)z + \(\frac{7}{10}\) |
