Question

решить уравнение 797-y=340•2
160+y=310•2
192-x=440:4
x+18=220:2​

Answer 1

1)

$797 - y = 680$

$- y = 680 - 797$

$- y = - 117$

$y = 117$

2)

$160 + y = 620$

$y = 620 - 160$

$y = 460$

3)

$192 - x = 110$

$- x = 110 - 192$

$- x = - 82$

$x = 82$

4)

$x + 18 = 110$

$x = 110 - 18$

$x = 92$
