Question

draw the graph of the following equations and check whether (a) x=2, y=5 (b) x=-1,y=3 are solution of 2x+5y=13

Answer 1

Answer:

hey mate

2x +5y = 13 ( where x= -1, y=3)

2×-1 + 5×3=13

-2+15=13

13=13

(b) is the solution of the equation

hope it will help you

Answer 2

Answer:

a )  x=2, y=5

2x+5y=13

LHS = 2 * 2 + 5 * 5 = 29 which is not equal to 13

LHS is not equal to RHS

therefore it is not the solution of 2x+5y=13

b ) x=-1,y=3

2x+5y=13

LHS =2 * - 1 + 5 * 3 = 13 = RHS

therefore it is the solution of 2x+5y=13

if the answer is useful pls mark as brainliest..........plssss
