If you change the x with the 11 and the y with 7, you subtract the 8 from 11, than add 4 times 7. And you get 31

Daniel spent $4.75 for a lunch and $1.85 for a snack
$4.75+$1.85=$6.6, so Daniel spent $6.6 total

Kyle spent $5.75 for lunch and $1.00 for a snack
$5.75+$1.00=$6.75, so Kyle spend total $6.75.

Final step:
$6.75-$6.6=$0.15. As a result, Kyle spent $0.15 or 15 cent more than Daniel. Hope it help!

Since the total measurements of triangle corners are equal to 180

Then

2x + 3x - 10 + 50 = 180 \\ 5x - 40 = 180 \\ 5x = 140 \\ x = 28

Solve the system of equations 2r + 2s = 50 and 2r – s = 17.
WARRIOR [948]
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
