Answer:
Option B
Step-by-step explanation:
We have to solve the equation by elimination method equations are
5x + 3y = 31 --------(1)
2x + 3y = 25 --------(2)
Now we subtract equation (1) from (2)
( 5x + 3y ) - ( 2x + 3y ) = 31 - 25
( 5x - 2x ) + ( 3y - 3y ) = 6
3x = 6
x = 2
Now we put x = 2 in equation (1)
5 × 2 + 3y = 31
10 + 3y = 31
3y = 31 -10
3y = 21
y = 7
Solution is ( 2, 7 )
Therefore, Option B is the answer.
