First, you want to divide both sides by 3 to isolate your variable. You get x^2 = 9. The square root of x^2 and 9 equals x = 3.
x = 3 is your answer.
Answer
16=3x
Step-by-step explanation:
Each side has x
there is 3 sides
so 3x will equal 16.

<h3>What is an
equation?</h3>
An equation is an expression that shows the relationship between two or more numbers and variables.
She wants to buy a sofa for $924 and a coffee table for $640, hence:
Estimated total cost = 924 + 640 = $1564
The Estimated total cost was $1564. Zara do not have eough money to buy the sofa and coffee table.

Answer:
x = - 5, x = 2
Step-by-step explanation:
Using the rules of logarithms
log x - log y = log (
)
x = n ⇔ x = 
note that log x = 
x
Given
log (x² + 3x) - log10 = 0, then
log(
) = 0, thus
= 
= 1 ( multiply both sides by 10 )
x² + 3x = 10 ( subtract 10 from both sides )
x² + 3x - 10 = 0 ← in standard form
(x + 5)(x - 2) = 0 ← in factored form
Equate each factor to zero and solve for x
x + 5 = 0 ⇒ x = - 5
x - 2 = 0 ⇒ x = 2
Solution is x = - 5, x = 2
