Answer:
20x = 55
Step-by-step explanation:
First you have to add 3x to both sides of 11-3x=x

Now that you have 11 = 4x you divide 4 on both sides 
11/4 = x
But you can't divide 11 by 4 unless you are looking for the decimal form of 11/4 which is 2.75
so now we take 11/4 or 2.75 depending on if you need your answer in fraction or as a decimal and replace that with x however both will equal the number 55
Answer:
x = 36
Step-by-step explanation:
<em>A triangle has 180°</em>.
That <em>third angle is 360 - 8x</em>.
So the equation is: <em>180 = 2x + x + 360 - 8x</em>.
Simplify: 180 = -5x + 360
Add/Subtract: 5x = 180
Divide: x = 36.
Answer:
Step-by-step explanation:
Remember simple multiplication? Write the problem with 17 at the bottom:
8
* 1 7
----------
5 6 <-- this is 8*7
8 0 <-- this is 8*10 [we sometimes just shift and don't write the 0]
-------
1 3 6
So, 8*17 is the same as 8*10 + 8*7.
