Question

решите уровнение 3y=6+2y    10-7x=7-x 6x=4x+10 t+6.8=9t+10 x+2=4-x 1+2.6z=6+3z 3x+1=5x-3 2x-3=2-3x

Answer 1

3y=6+2y

3у-2у=6

у=6

10-7x=7-x

-7х+х=7-10

-6х=-3

х=0,5

6x=4x+10

6х-4х=10

2х=10

х=5

t+6.8=9t+10

t-9t=10-6.8

-8t=3.2

t=-0.4

 

x+2=4-x

х+х=4-2

2х=2

х=1

1+2.6z=6+3z

2.6z-3z=6-1

-0.4z=5

z=-12.5

3x+1=5x-3

3х-5х=-3-1

-2х=-4

х=2

2x-3=2-3x

2х+3х=2+3

5х=5

х=1
