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