Question

8-3x=17 solve for x and check your answer.

Answer 1

Answer: -3

Step-by-step explanation:

8-3x=17

-8 on both side to cancel it out

-3x=9

divide -3 on both sides

which would equal to -3

To check

8-3(-3)=17

8+9=17

17=17

Answer 2

Answer:

x = 3

Step-by-step explanation:

8 - 3x = 17

You have to switch the 8 to the other side. To do this, you would have to move it after the 17 and add a minus to it, making it a -8 (this is because when a number is switched to the other side of the '=' sign, the number gets 'mirrored' aka positive numbers become negative and negative numbers become positive).

3x = 17 - 8

3x = 9

Now you have to do the same thing you did with 8 but instead you have to do it with 3. Since 3 has an invisble 'times sign' by it, the number after the equals will be divided by 3 in this case so...

x = 9 ÷ 3

x = 3
