First one is correct value

Second one is wrong value...

Check this...

Let's put the value of x...

5x + 3 = 13

(5 × x) + 3 = 13

(5 × 2) + 3 = 13

10 + 3 = 13

13 = 13

LHS = RHS

Therefore the value of x is correct

Now let's put value of y....

7y + 3 = 17

(7 × y) + 3 = 13

(7 × (- 3)) + 3 = 13

(-21) + 3 = 13

-18 ≠ 13...

LHS ≠ RHS

Therefore the value of y is incorrect...
