Answer:

6,3

Step-by-step explanation:

given equtions are

x+3y=15______(1)

4x+2y=30______(2)

multiplying (1) by 4

on solving, 4x+12y=60_____(3)

substracting eqution (3) and (2)

4x+12y-(4x+2y)=60-30

⇒10y=30

on solving,

y=3

substituting the value of y in equation (1)

x+3(3)=15

on solving,

x=6
