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