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
