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 + b = 6b + 7z - 1 for b in terms of z.
| 6z + 5 | |
| 6z - 1 | |
| \(\frac{8}{11}\)z + \(\frac{9}{11}\) | |
| 1\(\frac{5}{6}\)z + \(\frac{1}{2}\) |
