Answer 2

Answer!

$x + x + x = 60 \\ 3x = 60 \\ x = \frac{60}{3} \\ x = 20 \\ 20 + x + x = 30 \\ 20 + 2x = 30 \\ 2x = 30 - 20 \\ 2x = 10 \\ x = \frac{10}{2} \\ x = 5 \\ x + 5 + x = 9 \\ 2x + 5 = 9 \\ 2x = 9 - 5 \\ 2x = 4 \\ x = \frac{4}{2} \\ x = 2 \\ 20 + x + 2 = 42 \\ 22 + x = 42 \\ x = 42 - 22 \\ x = 20 \\ 10 + 67 \times 2 = 144$
