Answer:

The number of girls is 128 and the number of boys is 83

Step-by-step explanation:

Let

x -----> the number of girls

y ----> the number of boys

we know that

[tex]x+y=211[/tex] ------> equation A

[tex]x=y+45[/tex] ----> equation B

substitute equation B in equation A and solve for y

[tex]y+45+y=211\\2y+45=211\\2y=211-45\\y=166/2\\y=83[/tex]

Find the value of x

[tex]x=83+45=128[/tex]

therefore

The number of girls is 128 and the number of boys is 83
