Question

2. Which equation is true when the value of x is 8?

6x - 20 = 32
16 - x = 12
20 - 0.4x = 13.8
1x + 12 = 30​

Answer 1

None.

Explanation:

6x-20=32

6(8)-20=48-20=28, not 32

--------------------------------------

16-x=12

16-8=8, not 12

--------------------

20-0.4x=13.8

20-0.4(8)=20-3.2=16.8, not 13.8

------------------------------------------------

1x+12=30

x+12=30

8+12=20, not 30
