16x + 15 = 463
16x = 463 - 15
16x = 448
x = 448 : 16
x = 28

x . 15 + x + 15 = 463
x . 15 + x . 1 + 15 = 463
x . ( 15 + 1 ) + 15 = 463
x . 16 + 15 = 463
x . 16 = 463 - 15
x . 16 = 448
x = 448 : 16

\(15x+x=463-15\)
\(16x=448\)
\(x=448:16\)
\(x=28\)
Đáp số x = 28.
Tíck cho mìk vs nha Erza Scarlet!
Cảm ơn mấy bạn rất nhiều nha
Thank you so much.......!
Ta có :
x.15+x+15=463
16x + 15 = 463
16x = 463 - 15
16x = 448
x = 448 : 16
x = 28
