Question

X+y=5
3x+2y=8 by elimination method

Answer 1

Answer:

x= -2

y=7

Step-by-step explanation:

multiply eq x+y=5 with 3

we get 3x+3y=15=>1

subtract eq 1-2

3x+3y=15

-3x-2y=-8

----------------

0+y=7 =>3

----------------

substitute eq 3 in any one eq(equation)

let us take eq 2=>3x+2y=8

3x+2(7)=8

3x +14=8

3x =8-14

3x = -6

x = -2
