Answer 1

Answer:

17) x=4

19)x= all real numbers

Step-by-step explanation:

Just switch the y for its give value

17) 4x-3(0)=16

3*0=0

4x=16

4x/4=16/4

X=4

19)-6x+3(2x)=0

3*2x=6x.

If you have - 6x and +6x then any number works for x.

Answer 2

Your answer to number 17 is x=4 because you replace y with 0 and you get 4x-3(0)=16. Then you multiply 3 by 0 to get 0 and get 4x=16 as ur equation. Then you can divide both sides by 4 to get 4 as your x.

Your answer to number 19 is 0 because 3(2x)-6x=0 is also known as 6x-6x=0 which equals 0.
