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