Answer:
X = 4
Step-by-step explanation:
And then the nearest tenth would be 0
cause all numbers that have 4 round to like 0 or the tenth under it. If it has a five or higher it rounds to 10 or the number above it
Eq1) 2r+2s=50
eq2) 2r-s=17
solve for s in equation2 (eq2)
-s=17-2r
s=-17+2r
Substitute s into equation1 (eq1)
2r+2(-17+2r)=50
2r-34+4r=50
6r-34=50
6r=50+34
6r=84
r=14
Substitute into either equation and solve for s
2(14)-s=17
28-s=17
-s=17-28
-s=-11
s=11
