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 + 5b = 9b - 8z + 5 for b in terms of z.
| -2\(\frac{3}{5}\)z - 1 | |
| \(\frac{13}{14}\)z - \(\frac{5}{14}\) | |
| z - \(\frac{1}{16}\) | |
| -5z - 2 |
