Question

are the following pairs of equations 3/5x​

Answer 1

Answer:

No, they are not equation

Answer 2

Answer:

The given equation are

2x−

4

3y

=3 and 5x=2y+7

Rearranging these equations we get,

8x−3y=12 .....(1)

5x−2y=7 ......(2)

multiply (1) by 2 and by 3 on subtracting we get

16x−6y=24

15x−6y=21

- + -

x − 0= 3

x=3

putting x=3 in (1) we get

8(3)−3y=12

24−3y=12

−3y=12−24

−3y=−12

y=−12/−3

y=4

hence x=3,y=4
