    so from the first sentence we have b+g=160 do you see that like b is the number of boys and g is the number of girls

    because g gets increased by 5%, so 1+(5/100)

    from the first equation you substract g from both sides, so: b= 160-g and then you substitute this value of b on the second equation: 160-g+1.05g=160+32 0.05g=32 g=32/0.05, are you sure its 5%, because the value of g, doesn't make sense....
