Question

What is correct solution for equations 2x + 5y = 19 and x – 3y = -7

(A) (2, 3) (B) (-2, -3) © (2, -3) (D) (-2, 3)​

Answer 1

checking option wise,

optionA

2x+5y=19

2×2+5×3=19

4+15=19

19=19

x-3y= - 7

2-3×3= -7

2-9= -7

-7= -7

if you don't want option wise checking, you can add both the equations and substrate them
