2. Anda diminta oleh menteri perhubungan merancang sebuah bandara untuk pesawat-pesawat kecil. Pesawat-pesawat yang akan digunakan di bandara tersebut harus mencapai kecepatan 27,8 ms-¹ atau 100 km/jam sebelum lepas landas. Berapa panjang minimum landasan yang harus dibuat agar pesawat dapat lepas landas?​

-4(3 + x) = -28
Clear the parentheses on the left side :
-12 - 4x = -28
Add 12 to each side:

4x = -16

Divide each side by -4 :
x = 4

you would multiply -4 and 3 and the multiply -4 and x and you would get -12-4x=-28 then add 12 to both sides and you would het -4x=-16 and divide -4 on both side and then answer would be x=4 because a negative divided by a negative is a positive hope i helped!

To solve − 4 ( 3 + x ) = − 28 , first distribute to get − 12 − 4 x = − 28 . Then isolate x by adding 12 to both sides and dividing by − 4 , leading to the solution x = 4 .
