Question

Реши уравнение 8 * x = 4216 и (30 - x) * 5 = 30

Answer 1

8*x=4216
x=4216/8
x=527
8*527=4216
4216=4216
Ответ : x=527
(30-x)*5=30
150-5x=30
-5x=30-150
-5x=-120
x=-120/(-5)
x=24
(30-24)*5=30
30=30
Ответ:x=24

Answer 2

• →$8*x=4216\\ 8x:8=4216:8\\ x=527$
• →$(30-x)*5=30\\ 150-5x=30\\ -5x=30-150\\ -5x=-120:-5\\ x=24.$
