plz answer fast​

Answer 1

Answer:

1)x=7/3

2)x=-0

3)x=3/2

4)x=0

Step-by-step explanation:

1) 3(x-1)+7=11

3x-3+7=11

3x+4 =11

3x =11-4

3x=7

x=7/3

2)20-(2x-5)=25

20-2x+5=25

20-2x=25-5

20-2x=20

-2x=20-20

-2x=0

x=-0

3)2x+1/4=7/4

2x=7/4 -1/4

2x=6/4

x=3/2......(multiplying both side by 2)

4)4(x+1)=4

4x+4=4

4x=4 -4

4x=0

x=0/4
