Question

2x+5y=24 ,4x+3y=20 in eliminaton method​

Answer 1

Answer:

x=2, y=4

Step-by-step explanation:

2x + 5y=24.......... (1)x3

4x + 3y=20..........(2)x5

6x+15y=72......(i)

20x+15y=100....(ii)

Subtract (i) from (ii)

20x-6x=100-72

14x=28

x=2

Substitute x in (1)

2*2 +5y=24

5y=24-4

5y=20

y=4.

Answer 2

Answer:

x=2 & y=4

Step-by-step explanation:

2(2x+5y=24)= 4x+10y=48

(4x+10y=48)-(4x+3y=20)=7y=28

y=28/7=4

2x+5×4=24

x=24-20÷2

=2
