Question

For which equation would x = 12 not be a solution?96 ÷ x = 89 x - 7 = 101x + 4 = 105 + 4 x = 53

Answer 1

Notice that:

1)

`(96)/(12)=8.`

Therefore x=12 is a solution to

`96/ x=8.`

2)

`9*12-7=108-7=101.`

Therefore x=12 is a solution to:

`9x-7=101.`

3)

`12+4=16\\e10.`

Therefore x=12 is not a solution to:

`x+4=10.`

4)

`5+4*12=5+48=53.`

Therefore x=12 is a solution to:

`5+4x=53.`

Answer: Third option:

`x+4=10.`
