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 2b + 7b = 4b + 3z + 5 for b in terms of z.
| \(\frac{9}{11}\)z - \(\frac{3}{11}\) | |
| -1\(\frac{1}{2}\)z + 2\(\frac{1}{2}\) | |
| 2z - 2\(\frac{1}{2}\) | |
| \(\frac{1}{9}\)z + \(\frac{1}{9}\) |
