: -3x+1=5-2x
I know the answer is -4 because it is in the back of the book. can you please explain very detailed how they get this answer. I have a learning disability so I need very detailed and basic step by step instructions on how to work it.
Thank you very much This question is from textbook elementary and intermediate algebra
You can put this solution on YOUR website! -3x + 1 = 5 - 2x
:
We want to isolate x on the left by performing algebra operations on both sides
:
Add 2x to both sides
-3x + 2x + 1 = 5 - 2x + 2x
;
Do the math on like terms and we have
-1x + 1 = 5
:
subtract 1 from both sides
-x + 1 -1 = 5 - 1
:
which is
-x = 4
:
We have to have the variable (x) to be positive, multiply both sides by -1
-1(-x) = -1(3)
:
x = -4
:
:
Check solution in the original equation, substitute -4 for x
-3(-4) + 1 = 5 - 2(-4)
+12 + 1 = 5 + 8
13 = 13 proves our solution is correct
