Question

Решите уравнение x-3,243=5,1 и (y+2,84)-1,81=6,4

Answer 1

x-3,243=5,1
x = 5.1 + 3.243
x = 8.343
(y+2,84)-1,81=6,4y + 2.84 = 6.4 + 1.81
y + 2.84 = 8.21
y = 8.21 - 2.84
y = 5.37

Answer 2

$1)x-3.243=5.1\x=5.1+3.243\x=8.343 \ \ 2)(y+2.84)-1.81=6.4\y+2.84=6.4+1.81\y+2.84=8.21\y=8.21-2.84\y=5.37$
