Question

5y −2x = −15 solve by elimination method

Answer 1

Answer:

Correct option is

A

x=15,y=10

Given,

15

2x

+

5

y

=4;

3

x

=

2

y

Rewriting the given equations, we get

2x+3y=60 ...(i)

2x−3y=0 ...(ii)

On adding (i) and (ii) , we get

4x=60

⇒x=15

On putting x=15 in (i), we get

2(15)+3y=60

⇒y=10

∴x=15,y=10
