Question

elimination method x+y=3 & 2x-3y=20

Answer 1

Hey friend !! Here is your answer

__________________________

◆x+y=3--------(1)

◆2x-3y=20--------(2)

◆By elimination

◆Equation (1) × 2

So,

2x+2y=6-----(3)

◆Equation (3)-(2)

◆-5y=14

◆y=-14/5

---> Put in equation (1)

◆x+(-14/5)=3

◆Take LCM

◆5X-14/5=3

◆5X-14=5×3

◆5x=15+14

◆5x=29

◆x=29/5
