Answer 1

Answer:

8,10.

Step-by-step explanation:

2x+3y=46.....(1)

3x+5y=74.....(2)

multiply equation (1)and(2) by 3 and 2 respectively.

thus we get,

3(2x+3y=46)

6x+9y=138.....(3)

2(3x+5y=74)

6x+10y=148...(4)

thus subtracting equation (3)and(4) we get,

y=10

now, substitute y=1 in eq(1)

2x+3y=46

2x+3(10)=46

2x+30=46

2x=46-30

2x=16

x=16/2

x=8

thus x= 8,y=10
