Answer 1

Answer:

$\huge\boxed{\fcolorbox{red}{Yellow}{Correct answer}}$

Step-by-step explanation:

(1) 14x+21+40x+8=39x+65+4x+8

54x+29-43x-73=0

11x-73+29=0

11x-44=0

x=4

Answer 2

7(2x + 3) + 8(5x + 1) = 13(3x + 5) + 4(x + 2)

14x + 21 + 40x + 8 = 39x + 65 + 4x + 8

54x + 29 = 43x + 73

54x - 43x = 73 - 29

11x = 44

x = 4
