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