How do you solve #4 - (2x - 9)= -19#?

Answer 1

Eli Assouline

By going through the problem like an equation getting #x# by itself.

I'm just going to go step by step explaining each step.

#4-(2x-9)=-19# is our original equation.

Now I'm going to get rid of the parenthesis by distributing the negative outside of it.

#4-2x+9=-19#

Now I'm going to gather like terms.

#13-2x=-19#

Now I'm going to get #2x# by itself so we can solve for #x# by subtracting #13# from each side.

#-2x = -32#

Now I'm going to divide each side by #-2# to get #x# by itself, and that will get us our final answer.

#x = 16#

To solve the equation 4 - (2x - 9) = -19, first distribute the negative sign within the parentheses. This yields 4 - 2x + 9 = -19. Then, combine like terms by adding 4 and 9, which gives 13. Rewrite the equation as 13 - 2x = -19. Next, subtract 13 from both sides to isolate the variable term, resulting in -2x = -32. Finally, divide both sides by -2 to solve for x, giving x = 16.

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.
