Question

3x÷2-5y÷3=-2 solve the pair of linear equation by substitution method​

Answer 1

The value of x is 2 and y is 3.

Step-by-step explanation:

……………………..(1)

……………………….(2)

Consider equation

 By taking LCM for the denominator 2 and 3 we get the LCM as 6

9x – 10y = -12 ……………………….. (3)

Consider equation 2

By taking LCM for the denominator 3 and 2 we get the LCM as 6

2x + 3y = 13 …………………………(4)

By solving equation (3) and (4) we get

2x = 13-3y

x=13-3y/2 …………………………(5)

Put the value of x in eqn 3 we get

9[13-3y/2] – 10y =-12

117-27y-20y = -24                  [By taking LCM and solving it]

117-47y=-24

-47y=-24-117

-47y=-141

Y=-141/-47

Y=3

Now put the value of y =3 in (5)

x=13-3(3)/2

x=13-9/2

x=4/2

x=2

Therefore we have x=2 and follow me ✌️ samile ✌
