jadi, 4x5=2+x. 20=2+x. x=20/2=10.
4kali5 maksudnya
2 + x/4 = 5
2 + x/4 = 5
x/4 = 5-2
x/4 = 3
x = 3.4
x = 12
kalo x nya 12, coba aja masukin ke soalnya. 2 + x(12) per 4 = 5. 2+12 per 4 apakah hasilnya akan 5?

-5x -4x +10 = 1 -5x-4x = 1-10 -9× = -9 x= -9/-9 x=1

-5x + 4x + 10 = 1
-x + 10 = 1
-x = 1-10
-x = -9
x = 9
