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 3b + 5b = 7b - 3z + 2 for b in terms of z.
| -\(\frac{7}{8}\)z + \(\frac{3}{4}\) | |
| 13z - 3 | |
| -z - \(\frac{7}{12}\) | |
| 2z - \(\frac{1}{2}\) |
