Question

solve ... 2x + 3y= 1 ; x- 2y= -12​

Answer 1

Step-by-step explanation:

2x + 3y = 1

(2 × -2) + ( 3 × -12 ) =1

-4 + -36 = 1

-4 = 1 + 36 = 37

answer is 37 + 4 = 41

Answer 2

Answer:

x=38/7

y=25/7

Step-by-step explanation:

let 2x+3y=1. (1)

x-2y= -12. (2)

by substitution method

eq. (2)=> x= -12+2y. (3)

substituting (3) into (1) we get,

2( -12+2y)+3y=1

=> -24+4y+3y=1

=>7y=25

=> y=25/7

putting the value of y in eq. (3) we get,

x= -12+2(25/7)

=> x= -12+50/7

=> x=> 38/7.
