How do you solve #-13=5+x#?

Answer 1

Avery Alexander

#x=-18#

Our only step would be to subtract #5# from both sides to undo the operation being applied to #x#. Doing this, we get

#x=-18#

We can plug in our answer for #x# to check this solution. We have

#-13=5+color(lime)(x)#

#-13=5+color(lime)((-18))#

#-13=-13#

I hope this is useful.

To solve -13 = 5 + x, subtract 5 from both sides of the equation. This gives you: -13 - 5 = x. Simplify the left side of the equation to get: -18 = x. Therefore, x = -18.

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.
