Answer:
150 boys
Step-by-step explanation:
equation:
⇒ 5x + 4x = 270
add like terms:
⇒ 9x = 270
divide 9 on both sides:
⇒ [tex]\frac{9x}{9} = \frac{270}{9}[/tex]
solve:
⇒ x = 30
take original equation and subtitute 30 for x;
⇒5 x 30 + 4 x 30 = 270
⇒ 150 + 120 = 270
We can see that if there were 270 students, 150 would be boys and 120 would be girls.
