triplea59

Answer:

the explanation is in the diagram

if you noticed I multiplied the second equation all through by minus so the positive 9 turned negative when multiplied by minus so negative 14 + negative 9 gives negative 23

Step-by-step explanation:

32-2y=22

y=5 because 32 minus 10 is 22 and 2y is 10

7x + 3y= 105

same as

7x + 15 = 105

7x = 90

X = 90/7

X = 12.8571429

X+y= 17.8571429

brainliest?
