Solve:-2x+y=5 and 3x÷3y=10 using elimination method

Answer»

y=5/3

x=1

Step-by-step explanation:

2x+y=5 -----eq(1)

3x+3y=10------eq(2)

[MULTIPLYING each equation with the CORRESPONDING no to eliminate one VARIABLE]

(2x+y=5)*3

(3x+3y=10)*2

[after MULTIPLICATION]

6x+3y=15

6x+6y=20

+ - -

________

-3y= -5

y=5/3----eq(3)

PUTTING value of eq(3) in eq(1)

2x+5/3=5

10x+5/3=5

10x+5=5*3

10x+5=15

10x=15-5

10x=10

x= 1
