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 - 5b = -7b - 2z - 6 for b in terms of z.
| -\(\frac{1}{4}\)z + \(\frac{3}{4}\) | |
| \(\frac{9}{10}\)z - \(\frac{3}{10}\) | |
| 1\(\frac{3}{7}\)z + \(\frac{5}{7}\) | |
| 3z - 6 |
