Answer 1

p=3

5×3+2=17

mark me as brainliest

Answer 2

$\longrightarrow{\blue{ p=3 }}$ 

Step-by-step explanation:

$5p + 2 = 17$

Substituting different values for p, we have

When $p = 1$

$= 5 \times 1 + 2$

$= 5 + 2$

$= 7$

$≠R. H. S$

When $p = 2$

$= 5 \times 2 + 2$

$= 10 + 2$

$= 12$

$≠R. H. S$

When $p = 3$

$= 5 \times 3 + 2$

$= 15 + 2$

$= 17$

$= R. H. S.$

For "$p = 3$", L. H. S. = R. H. S.

Hence, the required solution is $p= 3$.
