Question

10) 5x+6y=9,3x+2y=5 solve using elimination method​

Answer 1

Step-by-step explanation:

5x+6y=9-------------(1)

3x+2y=5-------------(2)

-----(1)*3

-----(2)*5

15x+18y=27-------1

15x+10y=25------2

(-). (-). (-). ------------ change the symbols.

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

0+8y=2-------------3

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

y=2/8=1/4

subsisting the value of y in equation 3

3x+2(1/4) =5

3x+2/4=5

then

3x=5-2/4

3x=18/4

x=18/4 divided by 3

then reciprocal

x=18/4*1/3

18 goes 6 time in 3

then

x=6/4=3/4

Therefore,x=3/4 and y=1/4.

I hope this is the correct answer.

thank you
