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 7b - 7b = b + 8z + 7 for b in terms of z.
| \(\frac{2}{5}\)z - 1\(\frac{3}{5}\) | |
| -\(\frac{3}{4}\)z + \(\frac{3}{4}\) | |
| 11z + 2 | |
| 2\(\frac{1}{2}\)z + 1\(\frac{1}{6}\) |
