4. – 2y = -5
10.x + 20y = -2

10 • (x - 2y + 3z)

? if thats the answer.

and   y = 5/2 = 2.500 for the - 2y = -5 one. if they are both combined please comment under mine.

The fraction of the girls signed up to play outfield is

Solution:

Given that Two fifths of the girls in school signed up to play softball

An equal number of girls signed up to play pitcher, infield and outfield
