Answer and Explanation:
I'm assuming you mean the "Additive property of equality".
The additive property of equality states if the same value amount is added to both sides of an expression or equation, it will remain equal.
Similarly, the additive property of inequalities states if the same value amount is added to both sides of an inequality, it will remain true.
Answer:
Step-by-step explanation:
Since (8x-20) and (3x+2) are two sides of the angles on one plane, we can structure them into an equation to find x.
(8x-20) + (3x+2) = 180
We want x to be on one side and all the numbers to be on the other. But first, we must combine our two problems.
-20 + 2 = -18; 8x + 3x = 11x
So now our equation is:
(11x-18) = 180
In order to move our numbers to one side and leave our x's on the other, we must inverse our additions/subtractions/etc.
180 + 18 = 199
11x = 199
199/11 = 18.1
x=18.1!
