Here! (x+4)+(x+2)+(x+5)= (x+1)+(x+1)+(x+3)+(x+3) First you want to write the whole equation out. Make each perimeter equal to each other. Then add both sides separately. (x+4)+(x+2)+(x+5) =3x+11
and
(x+1)+(x+1)+(x+3)+(x+3) =4x+8
Now that you've simplified each side, solve like a normal equation. 3x+11 = 4x+8 -3x -3x 11 = x+8 -8 -8 3=x
Lets get common fractions between 1/10 and 1/4, so we now have the fractions 2/20 and 5/20. After we add them we have 7/20. If 35% (7/20) of the points scored is 21, then total points scored is 60. (21 / .35)
