➷ T\boxed{4} B\boxed{24}

✽ Ok, so B is the number of boys and T is the number of teachers.

➷ t \div ( B + 18) = \frac{2}{21}

\frac{B}{18} = \frac{4}{3}

✽ Then solve the second equation for B.

➷ B = 24

✽ Plug into the first equation to find T.

➷ T \div (24 + 18) = \frac{2}{21}

T = 4

✽

➶ Hope This Helps You!

➶ Good Luck (:

➶ Have A Great Day ^-^

Solve the equation<br> 13-4x=1-x
dem82 [27]
Add 4x to both sides and get
13 = 1 + 3x
12 = 3x   [from subtracted 1 from both sides]
x = 4      [from dividing 3 from both sides]

therefore your answer would be  x = 4
