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 = 5b - 3z - 5 for b in terms of z.
| -\(\frac{1}{10}\)z - \(\frac{1}{2}\) | |
| 1\(\frac{2}{3}\)z + 2\(\frac{2}{3}\) | |
| \(\frac{3}{4}\)z + \(\frac{5}{12}\) | |
| -1\(\frac{2}{7}\)z - \(\frac{4}{7}\) |
