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 - 6b = 8b - 7z + 1 for b in terms of z.
| -\(\frac{2}{13}\)z - \(\frac{6}{13}\) | |
| z - 1 | |
| z - \(\frac{7}{8}\) | |
| -\(\frac{5}{12}\)z + \(\frac{5}{12}\) |
