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 -5b - 7b = -6b - 6z + 5 for b in terms of z.
| -1\(\frac{2}{11}\)z - \(\frac{2}{11}\) | |
| -1\(\frac{1}{2}\)z + 2 | |
| z + 5 | |
| 3\(\frac{3}{4}\)z - 1\(\frac{1}{4}\) |
