Question

(3x+7)•2=32
(2x-20):32=6
(42+2x):2=32
(13-2x)•3=27

Answer 1

(3х+7)×2=32
3х+7=32÷2
3х+7=16
3х=16-7
3х=9
х=9÷3
х=3

(2х-20)÷32=6
2х-20=6×32
2х-20=192
2х=192+20
2х=212
х=6

(42+2х)÷2=32
42+2х=32×2
42+2х=64
2х=64-42
2х=22
х=11

(13-2х)×3=27
13-2х=27÷3
13-2х=9
2х=13-9
2х=4
х=2

Answer 2

1) 3 2) 6 3) 11 4) 2
