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 3b + 7b = 4b + 6z - 3 for b in terms of z.
| z + 3 | |
| -15z + 7 | |
| -7z - 4 | |
| \(\frac{4}{11}\)z - \(\frac{6}{11}\) |
