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