Very easy question.
To find x intercept: Multiply y by 0. You get x=-5.
To find y intercept: Multiply x by 0. You get y=-5.
Let smaller no be x and bigger be y
- x+y=39--(1)
- 3x=y+81
- y=3x-81
- y=3(x-27)--(2)
Put it in eq(1)
- x+3(x-27)=39
- x+3x-81=39
- 4x=81+39
- 4x=120
- x=30
Now
The numbers are 9 and 30
Combine like terms : 8y = 16
Divide by 8 on both sides : y = 2
