Question

5 x + 7 Y is equal to 17 and 3 x minus 2 Y is equals to 4

Answer 1

If you want to find the value of x and y then following elimination method can be used.

STEP BY STEP EXPLANATION-

5x+7y=17--------------------eq 1
3x-2y=4---------------------eq 2

Multiplying by 2 in eq 1 and by 7 in eq 2,then adding equation 1 and 2-

10x+14y=34
21x-14y=28
----------------
31x=62
x=2..Ans

Putting x=2 in equation 1
5×2+7y=17
10+7y=17
7y=7
y=1...Ans

Therefore x=2 and y=1

Answer 2

Answer:

The value of x and y is 2 and 1.

Step-by-step explanation:

As per the data given in the question we have to find value of X and Y.

As per the questions it is given that 5 x + 7 Y is equal to 17 and 3 x minus 2 Y is equals to 4

If you want to find the value of x and y then following elimination method can be used.

5x+7y=17-------------------- (1)

3x-2y=4---------------------(2)

Multiplying by 2 in eq 1 and by 7 in eq 2,to find the value of x.

10x+14y=34

21x-14y=28

----------------

31x=62

⇒x=2

Putting x=2 in equation 1

5×2+7y=17

⇒10+7y=17

⇒7y=7

⇒y=1

So, the value of  x=2 and y=1.

Hence, the value of x and y is 2 and 1.
