Answer: the answer is 18
Step-by-step explanation:
It is a double negative so just show below this equation
9-(-9)
9+9. Because of double negative
18
X is a variable, a variable you have to divide to cancel out
Answer:
x = 6
Step-by-step explanation:
Verticle angles are formed when two lines intersect. The angles opposite each other are congruent, those angles are called vertical angles.
Using this knowledge, one can say;
3x + 2= 20
Use inverse oeprations to solve for "x"
3x + 2 = 20
-2 -2
3x = 18
/3 /3
x = 6
We make use of 
to solve for y, when you know x and z
<h3>How to solve for y?</h3>
The expression is given as:
x^y = z
The above expression is an exponential expression.
Start by taking the logarithm of both sides
y log(x) = log(z)
Divide both sides by log(x)
Hence, we make use of to solve for y, when you know x and z
