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 7b + 5b = -2b - 8z - 3 for b in terms of z.
| -2z + 6 | |
| \(\frac{1}{3}\)z + 1\(\frac{1}{3}\) | |
| -\(\frac{4}{5}\)z + \(\frac{3}{5}\) | |
| -1\(\frac{4}{9}\)z - \(\frac{1}{3}\) |
