Algebra problem help!?
Please explain how you got your answer and include all the steps so I can properly understand it. Thank you.
2x - 3(-2x + 4) = -13 + x
I have plugged -1/7 into the equation about 3 times now and calculated it and they come out unequal each time.
Never mind I got it! thanks for the help.

2x - 3(-2x + 4) = -13 + x
So now you want to get rid of the brackets so you multiply each of the items in the bracket with -3
2x + 6x - 12 = -13 + x
Now you want all the x on the same side and just the numbers on the other
2x + 6x - x = -13 + 12
7x = -1
Now you divide both sides by 7
x = -1/7
And you put -1/7 for each x and see if your answer is correct.

you have to first multiply the -3 by the two in ( ). so now you have
2x +6x - 12 = -13 + x now you add the x's together and all the numbers. so now you have:
8x -12 = -13 +x and then you move all the x's to one side and all the numbers to the other
8x - x = 7x and -13 + 12 = -1 so now oyu have 7x=-1 divide 7 from both sides to get
x = - 1/7
