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 6b - 4b = 4b + 3z + 7 for b in terms of z.
| 3\(\frac{1}{2}\)z + 3\(\frac{1}{2}\) | |
| \(\frac{1}{8}\)z - \(\frac{1}{4}\) | |
| z + \(\frac{9}{13}\) | |
| z + \(\frac{3}{5}\) |
