How do you solve #- 5x – 7 = - 3x + 1#?

Answer 1

Kennedy Adams

#color(blue)(x =-4#

#−5x–7=−3x+1#

#−5x+3x = 7+1#

#−2x =8#

#x =8/(-2)#

#x =cancel8/(-cancel2)#

#color(blue)(x =-4#

To solve the equation -5x - 7 = -3x + 1, first combine like terms to get -5x + 3x = 1 + 7. This simplifies to -2x = 8. Then, isolate the variable by dividing both sides by -2, giving x = -4.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
