Решите уравнения пж

Answer 1

1) 4х - 3х = 6 - 5; х=1

2) 5х - 3х = 4; х=2

3) 2х - х = 8 - 5; х=3

4) -3 - х= - 9+ 1; -4х = - 8; х = 2

5) 6х - 3х = 8+7; 3х = 15; х = 5

6) 4х - 2х= 10 + 2; 2х =12; х=6

7) 6х - 4х = 17 -3; 2х = 14; х = 7

Answer 2

$1) : 4x - 3x = 6 - 5 \ x = 1 \ 2) : 5x - 3x = 1 + 4 \ 2x = 5 \ x = 2.5$
$3) : 2x - x = - 5 + 8 \ x = 3 \ 4) : - 3x - x = 1 - 9 \ - 4x = - 8 \ x = 2$
$5) : 6x - 3x = 8 + 7 \ 3x = 15 \ x = 5 \ 6) : 4x - 2x = 10 + 2 \ 2x = 12 \ x = 6$
$7) : - 4x + 6x = 17 - 3 \ 2x = 14 \ x = 7$
