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 2b + 5b = 5b + 6z - 9 for b in terms of z.
| -\(\frac{1}{3}\)z - \(\frac{2}{15}\) | |
| -\(\frac{1}{3}\)z + 3 | |
| -3z + 1 | |
| \(\frac{5}{11}\)z - \(\frac{4}{11}\) |
