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 -4b + 6b = -9b - 5z - 3 for b in terms of z.
| -2\(\frac{1}{5}\)z - \(\frac{3}{5}\) | |
| \(\frac{3}{16}\)z - \(\frac{7}{16}\) | |
| -1\(\frac{1}{6}\)z + \(\frac{1}{3}\) | |
| \(\frac{2}{7}\)z - \(\frac{5}{7}\) |
