How do you solve #9(x+9)=90# using the distributive property?

Answer 1

#x=1#

Using the distributive property (by distributing the #9# to #(x+9)#) We get #9x+81=90# Subtract #81# from both sides get #9x=9# So #x=1#

To solve 9(x + 9) = 90 using the distributive property, you first distribute the 9 to both terms inside the parentheses:

9(x + 9) = 9x + 81

Now, you have the equation 9x + 81 = 90. To isolate the variable term, you subtract 81 from both sides:

9x + 81 - 81 = 90 - 81

This simplifies to:

9x = 9

Finally, to solve for x, you divide both sides by 9:

9x / 9 = 9 / 9

This gives:

x = 1

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.
