Question

solve the following pair of linear equations: (i) 3x+4y=10 (ii)2x-2y=2​

Answer 1

⭐Solution⭐

✏given here

3x + 4y = 10.........(1)

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

multiply 2 and 3 in (1) and (2)

we get,

6x + 8y = 20..........(3)

6x -6y = 6............(4)

subtract its ,

14y = 14

=>y = 14 /14

=>y = 1

by (1)

3x + 4×1 = 10

=> 3x = 10-4

=> 3x = 6

=>x = 6/3

=>x = 2

✏Thus:-

Value of x = 2

Value of Y = 1

✏Hopes its help's u.

Answer 2

Answer:

x equal to - 18 and y equals to 16

Step-by-step explanation:

multiple by 2 in equation 1

and multiple by 3 in equation 2

then add both equation then we get vale of y equals to 16 then we calculated vale of a equals to -18
