Question

solve the following pair of linear equations by suitable method. 3x-y=3 and 5x-2y=4​

Answer 1

Answer:

x=2

y=3

Explanation:

according to question

5x-2y=4 and 3x-y=3 . these are the 2 equations that are given.

for finding the value of x put y=3x-3,

5x-2×(3x-3)=4

5x-6x+6=4

-x=4-6

-x= -2

so , x=2

now we know the value of x

put this value in 3x-y=3 equation for finding the value of x.

3(2)-y=3

6-y=3

6-3=y

3=y

so,

    the value of y=3.

Answer 2

Answer:

Answer:

x=2

y=3

Explanation:

according to question

5x-2y=4 and 3x-y=3 . these are the 2 equations that are given.

for finding the value of x put y=3x-3,

5x-2×(3x-3)=4

5x-6x+6=4

-x=4-6

-x= -2

so , x=2

now we know the value of x

put this value in 3x-y=3 equation for finding the value of x.

3(2)-y=3

6-y=3

6-3=y

3=y

so,

    the value of y=3.
