Answer:

x = 20

Step-by-step explanation:

6x - 10 = 3x + 50 {Vertically opposite angles}

6x = 3x + 50 + 10 {Combine like terms}

6x = 3x + 60 {Subtract 3x from both sides}

6x -3x = 60

3x = 60 {Divide both sides by 3}

x = 60/3

x = 20

Not equivalent

Step-by-step explanation:

Distribute the negative in the parentheses. It basically multiplying everything inside by -1.

$( \frac{1}{2} + 6x + 3)$

add like terms
