Of the following equations are equivalent? 2+x=5,x+1=4,9+x=6,x+(4)=7,-5+x=-2

sorry I cannot give the answer of this question

1.

Step-by-step explanation:

4/7=12/x-3

=>1/7=3/x-3

=>x-3=21

Multiplying both sides by 4

4(x-3)=4x21

=>4x-12=84

Hence Option 1 is yoir answer

3x + 4y = 15

answer = 3.

Step-by-step explanation:

4/7= 12/x-3

4/7×12=x-3

48+21/7 =x

69/7= x

1. 4x-12=28

4x = 28+12=40

x = 40/4=10

2.28= 12x-36

28+36 =12x

64/12= x

3. 48= 7x -21

48+21=7x

69 =7x

69/7 =x

this is equivalent to 4/7 = 12/x-3

4. 4x-3=84

4x = 84+3=87

x = 87/4

answer:

-6y=9-4x

6y=-9+4x

y=2/3x-3/2

answer:

I think the ans is c
