Takeshi claims that the solution to the equation 2x - 2(4x - 3) = 6x + 12 is x = -0.5. He shows the steps below to justify his solution. Given: 2x - 2(4x - 3) = 6x + 12
Step 1: 2x - 8x + 6 = 6x + 12
Step 2: -6x + 6 = 6x + 12
Step 3: -12x + 6 = 12
Step 4: -12x = 6
Step 5: x = -0.5

Step 1: Associative Property

Step 2: combining like terms

Step 3: combining like terms

Step 4: Reflexive Property of Equality

Step 5: Division Property of Equality

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
