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

Answer 1

10p-3p+4=4p+4+9
3p=9
p=3
To check answer put 3 in equation
10(3)-3(3)+4=4(3)+13
25=25

Answer 2

Given equation is 
10p - (3p - 4) = 4(p + 1) + 9

10p - 3p + 4 = 4p + 4 + 9

7p + 4 = 4p + 13

Writing like terms together

7p - 4p = 13 - 4

3p = 9

p = 3
