Question

10p-(3p-4)=4 (p+1)+9 solve it and check your answers
$10p - (3p - 4) = 4(p + 1) + 9$
solve the question and check your answer

Answer 1

10p-3p+4=4p+4+9
10p-3p+4=4p+13
7p-4p=13-4
3p=9
P=3
Now verification
10(3)-3(3)+4=4(3)+13
30-9+4=12+13
25=25
Hence verified

Answer 2

U can solve it simply as
10p-(3p-4)=4(p+1)+9
10p-3p+4=4p+4+9
10p-3p-4p=13-4
3p=9
p=3.
To verify ,you can put the value of p in the above equation,you will get left hand side value and right hand side value same.
