Question

3x+2y=13=5x-y solve in method of comparison

Answer 1

Answer:x=3 and y=2

Step-by-step explanation:

3x+2y=13____(1)

5x-y=13____(2)

Multiply 3x+2y=13 with 10

Multiply 5x-y=13 with 6

Then subtract equation (2) from eq (1)

30x+20y=130

30x-6y=78

(_) (+)=(-)

___________

26y=52

Y=2

Put the value of y in any equation

And you'll find that x=2

If you put it on eq(1)

3x+2y=13

3x+2×2=13

3x=9

X=3

(x,y)=(3,2)

Answer 2

Answer:

the correct answer is y = 2 and x = 3..
