Question

If 3x+7=x-1, then does x = -4?

Answer 1

Hey there!!

To check whether x= -4, let's solve the equation.

Given:

3x+7 = x-1

Subtracting 2x on both sides:

2x + 7 = -1

Subtracting 7 on both sides:

2x = -1-7

2x = -8

Dividing 2 on both sides:

x = -8/2

x = -4

Yes, x is -4.

Hope it helps!

Answer 2

Answer:

Yes

Step-by-step explanation:

You multiply 3 by -4 to get -12, then add 7 to make the left side of the equation -5. On the right side, all you have to do is do -4 minus 1, which is -5. That being said, yes x=-4
