Question

3x+5y=17 4x-5y=11 solution of the given pair of linear equation is​

Answer 1

Answer:

(4,1)

Step-by-step explanation:

3x+5y=17

4x-5y=11 adding both

7x=28 ,x= 4and y= 1

Answer 2

Given:

3x+5y=17

4x-5y=11

To find:

The solution of the equation

Solution:

The solution of the equation is (4, 1).

We have two equations that can be solved by adding the two to eliminate a variable.

The given equations are-

3x+5y=17

4x-5y=11

Since the coefficient of y is the same in both equations, we will add the two equations.

On adding, we get

7x=28

x=28/7

x=4

We will now put x=4 in the first equation to get the value of y.

3(4)+5y=17

12+5y=17

5y=17-12

5y=5

y=1

So, (x, y)=(4, 1).

Therefore, the solution of the equation is (4, 1).
