16 + 5x = 8x + 4

need the answer to be a whole number or decimal not a fraction etc.

x=4

Step-by-step explanation:

You first add like terms:

16-16+5x=8x+4-16

5x=8x-12

5x-8x=8x-8x-12

-3x=12

Now you divide to isolate the variable:

-3x/-3=-12/-3

Since the denominator and numerator are both negative, the answer will be positive:

x=4

Hope that made sense!

4

Step-by-step explanation:

(2x + 16) + (x) = 180

step-by-step explanation:

given,

abcd is a quadrilateral inscribed in a circle

angle a is labeled x plus 16, (x + 16)

angle b is labeled x degrees, (x)

angle c is labeled 6x minus 4, (6x – 4)

angle d is labeled 2x plus 16, (2x + 16)

what equation can be used to solve for angle b?

we know that the sum of the opposite angles of a simple quadrilateral inscribed in a circle is 180 degrees.

angle b is opposite angle d

therefore, angle b + angle d = 180

(x) + (2x + 16) = 180 

same as (2x + 16) + (x) = 180
