Question

5(3+h)-3(3+h)+10

Answer 1

5(3+h)-3(3+h)+10


15+5h-9-3h+10


2h+16



So 5(3+h)-3(3+h)+10 = 2h + 16

Answer 2

h = -8

Answer 3

15+5h-9-3h+10

2h+16

h=8

Answer 4

another method to this is let (3+h) = x so 5x -3x + 10 = 0 so 2x = -10..so x = -5.. substitute x back to 3 + h..3+ h = -5..h = -5-3 so h = -8
