\huge{\boxed{\mathcal\pink{\fcolorbox{red}{white}{Answer}}}}

Step-by-step explanation:

3x + 4y = 10 -  - -  - (<klux>1</klux>) \\ 2x - 2y = <klux>2</klux> -  -  -  - (2) \\

Now multiply 2 in equation (2)

we GET,

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

now eliminate equation (1) and (3)

3x + 4y = 10 \\ 4x - 4y = 4

___________________

7x = 14 \\ x = 2

now put the VALUE of x in equation (1)

3x + 4y =10

3 ×2 + 4y=10

y=1
