If 3x+7=x-1, then does x = -4?
2 answers:
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
<u><em>Yes, x is -4. </em></u>

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
