7(5x+8) + 12(x+4)

First , do 7 times 5x and 7 times 8
so you get:

35x + 56 + 12 (x+4)

now, do 12 times x and 12 times 4

35x + 56+ 12x + 48

combine like terms to get :

47x + 104 :]

7(5x+8)+12(x+4) = (35x+56)+(12x+48)
combining similar terms, we get

7(5x+8)+12(x+4) = (35x+12x)+(56+48)

adding
7(5x+8)+12(x+4) = 47x + 104

7(5x + 8) + 12(x + 4)
= 7*5x + 7*8 + 12*x + 12*4
= 35x + 56 + 12x + 48
= 35x + 12x + 48 + 56
= 47x + 104
