Use the elimination method to solve the system of equations. 5x - 2y = 9 and 3x + 4y = -5
2 answers:
Answer: Y = -2 and x = 1
Simplify:
10x − 4y = 18
3x + 4y = -5
Substitute and then the final answer is shown above.
Answer:
(1,-2)
Step-by-step explanation:
2(5x-2y=9) = 10x-4y=18
3x+4y=-5
4 cancels out then u add everything together
now u have 13x=13 the u divide 13x on both sides and you'll get x=1
now u plug xin to what ever equation u want i pick 3x+4y=-5
now u have 3(1)+4y=-5 then 3+4y=-5 then u subtract 3 on both sides and you get -8
now u have 4y=-8 then u divide and u get y=-2
x=1 y=-2
(1,-2)

3-6+12=9
Steps
you have to add first so you must add -6+12 which will be -6
Then you will take 3 - - 6 which will make it 9
Answer:
9
Step-by-step explanation:
the median is 9 and to keep it the same you put 9
