Step-by-step explanation:

what we want to find dude

Answer 2

Answer:

X=141/29 y=31/29

Step-by-step explanation:

7(y+3)-2(X+2)=15

7y +21 -2x -4 =15

7y -2x +17=15

7y-2x=15-17

7y-2x= -2...............(1)

similarly

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

4y-8 +3x-9 =2

4y+3x-17=2

4y+3x=2+17

4y+3x=19.......(2)

solve equations (1)and (2)

4×equation (1)

28y-8x=-8........(3)

and

7×equation (2)

28y+21x= 133.....(4)

Subtract equation (4) from (3)

(28y-8x)-(28y+21x)=(-8)-(133)

28y -8x -28y -21x = -8-133

-29x= -141

X=-141/-29

x=141/29

put value in equation (1)

7y-2x= -2

7y -2×(141/29) = -2

7y -282/29 = -2

7y = -2 +(282/29)

7y = (-58+282)/29

7y = 224/29

y=224/29÷(7)

y=31/29
