In elimination method you add/subtract both equations to cancel out a variable so you can solve for 1 variable.
since there is +y in the first equation and +y in the second equation, you can subtract both equations from eachother to only be left with x values:
(2x+y=11) (subtract each term)
- (x+y=9)
you get x=2.
now sub in x=2 to any of the 2 equations to find what y is.
2(2)+y=11
y=7
so the answer is (2,7) which means the 2 lines intersect at the point (2,7)
Answer:
D) is correct
Step-by-step explanation:
You can solve that by dividing 8 on both sides so you can isolate the variable y and know its value. So if you divide 8 on both sides, you'll get 4. 32 divided by 8 is 4. The answer is y = 4. Pick the first choice. I hope you find this answer the most helpful! :)
