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 + 4b = 7b - 8z - 8 for b in terms of z.
| -\(\frac{6}{7}\)z - \(\frac{3}{7}\) | |
| 5z - 2 | |
| \(\frac{9}{11}\)z + \(\frac{9}{11}\) | |
| z + \(\frac{2}{3}\) |
