Question

solve 2x+y = 5 and 3x +2y = 8
el​

Answer 1

Answer:

x = 2

y = 1

Step-by-step explanation:

Given : 2x + y = 5

3x + 2y = 8

So to make both side equation balance make both y value same, meaning multiplying up equation by 2 to make 2y also above, but in return we need to change plus to minus and minus to plus sign

So,

-4x -2y = -10

3x + 2y = 8

Now cancel positive and negative -2y on both side.

So,

-4x + 3x = -10 + 8

-x = -2

x = 2

Now substitute x value in of the equation to get y value i.e

3(2) + 2y = 8

6 + 2y = 8

2y = 8-6

2y = 2

y = 2/2

y = 1

Therefore x = 2 and y = 1.
