5x+4y=20.14<br> 6x+7y=28.15
ohaa [14]

Answer:

x=2.2582, y=19.91/9. (2.2582, 19.91/9).

Step-by-step explanation:

5x+4y=20.14

6x+7y=28.15

-------------------

6(5x+4y)=6(20.14)

-5(6x+7y)=-5(28.15)

------------------------------

30x+24y=120.84

-30x-35y=-140.75

--------------------------

-9y=-19.91

9y=19.91

y=19.91/9

5x+4(19.91/9)=20.14

5x+79.64/9=20.14

5x=20.14-79.64/9

5x=11.291

x=11.291/5

x=2.2582
