Question

2x-y=2. x+3y=15 solve by elimination method​

Answer 1

Answer:

2x-y=2---------(1)

x+3y=15----------(2)

so multiplying equation(2) with 2

so. 2x-y=2

2x+6y=30

(-) (-) (-)

—--—--------------------

0 -7y=-28

so (y=4)

so 2x-y=2

2x-4=2

2x=6

( x=3 )

hence x=3 and y=4

Answer 2

$\mathbb{ \ \ A\ N\ S\ W\ E\ R\: \: }$

2x - y = 2

x + 3y = 15

Solving both Equation we get

x = 3

y = 4
