Answer 1

Choice 1

Choice 4

Choice 5

Explanation:

For this one you just have to plug in the x in every equation and solve it. If the answer is true it's true, but if it's false it's false.

Let's solve each of these...

Number 1:

`9-3x=0\\9-3(3)=0\\9-9=0\\0=0`

As you can see 0 does equal itself so this one is true.

Number 2:

`3x+1=9\\3(3)+1=9\\9+1=9\\10\\eq9`

10 does not equal 9 so this one would be false.

Number 3:

`5x-7=1\\5(3)-7=1\\15-7=1\\8\\eq1`

This one is also false.

Number 4:

`2x+4=10\\2(3)+4=10\\6+4=10\\10=10`

This one is true.

Number 5:

`(x)/(3)+5=6\\((3))/(3)+5=6\\1+5=6\\6=6`

This one is true.

Number 6:

`(9)/(x)-1=4\\(9)/((3))-1=4\\3-1=4\\2\\eq4`

This one is false.
