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...
