Question

The solution to 3x - 7 = 14 is also a solution of which of the following equations? 5 x - 6 = 44 2 x + 12 = 28 3 x - 9 = 18 4 x - 12 = 16

Answer 1

Answer:

4x - 12 = 16

Step-by-step explanation:

The solution of the equation,

3x – 7 = 14

3x = 14 + 7

3x = 21

x = 21 / 3

x = 7

Put and check whether it satisfies the other equation.

We found that only equation 4x – 12 = 16

satisfies when we put x = 7

LHS = 4x – 12

= 4 (7) – 12

= 28 – 12

= 16

= RHS

Hope the solution is clear to you. :)

Answer 2

(1) 3x-7=14

3x=14+7

x=21/3

x=7

(2) 5x-6=44

5x = 44+6

5x=30

x= 30/5

x=6

(3) 2x+12=28

2x=28+12

2x=40

x=20

(4) 3x-9=18

3x=18+9

3x=27

x=9

(5) 4x-12=16

4x=16+12

4x=28

x=7
