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 8b + 7b = 7b + z - 8 for b in terms of z.
| \(\frac{1}{4}\)z + 1\(\frac{1}{8}\) | |
| -6z - 8 | |
| \(\frac{9}{10}\)z + \(\frac{3}{5}\) | |
| \(\frac{5}{9}\)z - 1 |
