5\left(x+5\right)-3\left(3+2x\right)+15=7-3x
Tenglamaning ikkala tarafini 15 ga, 3,5,15 ning eng kichik karralisiga ko‘paytiring.
5x+25-3\left(3+2x\right)+15=7-3x
5 ga x+5 ni ko'paytirish orqali distributiv xususiyatdan foydalanish.
5x+25-9-6x+15=7-3x
-3 ga 3+2x ni ko'paytirish orqali distributiv xususiyatdan foydalanish.
5x+16-6x+15=7-3x
16 olish uchun 25 dan 9 ni ayirish.
-x+16+15=7-3x
-x ni olish uchun 5x va -6x ni birlashtirish.
-x+31=7-3x
31 olish uchun 16 va 15'ni qo'shing.
-x+31+3x=7
3x ni ikki tarafga qo’shing.
2x+31=7
2x ni olish uchun -x va 3x ni birlashtirish.
2x=7-31
Ikkala tarafdan 31 ni ayirish.
2x=-24
-24 olish uchun 7 dan 31 ni ayirish.
x=\frac{-24}{2}
Ikki tarafini 2 ga bo‘ling.
x=-12
-12 ni olish uchun -24 ni 2 ga bo‘ling.
