Question

X-(500+79)=221 Pomogite reshitttttt

Answer 1

Решение.

х - (500 + 79) = 221

х - 579 = 221

х = 221 + 579

х = 800

Ответ: х = 800

Answer 2

$x - (500 + 79) = 221 \\ x - 500 - 79 - 221 = 0 \\ x = - 800 \\ x = 800$

Answer 3

Da, ya pomogu! Dlya resheniya etogo matematicheskogo vyrazheniya, nuzhno prosto provesti prostye arifmeticheskie deystviya:

X - (500 + 79) = 221

Najprezhde, vyrazhaem summu v skobkah:

X - 579 = 221

Teper' perekhodim k ispol'zovaniyu algebraicheskikh deystviy dlya opredeleniya X. Chtoby izbavit'sya ot vichitaniya 579, pribavim ego na obe storony uravneniya:

X - 579 + 579 = 221 + 579

X = 800

Poluchilos', chto X ravno 800. Esli u vas est' eshche kakie-libo voprosy, budu rad pomoch'.
