300 children are divided into 2 groups. there are 50 more children in the first group than in the 2nd group. how many children are there in the 2nd group?

Hei there!

Let's start by letting x be the number of children in the 2nd group. So we can make an equation:

(50+x)+x=300

Next, open parenthesis and combine like terms. Then solve for x.

50+x+x=300

2x=300-50

2x=250

x=125

So, there are 125 kinds in the 2nd group.

Hope I helped, sorry if I'm wrong ouo.

step-by-step explanation:

-8/2y-8=5/y+4-7y+8/y^2-16

we move all terms to the left:

-8/2y-8-(5/y+4-7y+8/y^2-16)=0

we can not solve this equation
