x = 7.5
Answer:
x = 4
Step-by-step explanation:
2x = 4x - 8
<em>subtract 2x from both sides of the equation</em>
2x - 2x = 4x - 2x - 8
0 = 2x - 8
<em>add 8 to both sides of the equation</em>
0 + 8 = 2x - 8 + 8
8 = 2x
<em>divide both sides of the equation by 2</em>
8/2 = 2x/2
4 = x

Answer: B. 40</h3>
For any triangle, the three angles always add to 180
(y+10)+(2y)+(50) = 180
3y+60 = 180 ... combine like terms
3y+60-60 = 180-60 ... subtract 60 from both sides
3y = 120
3y/3 = 120/3 .... divide both sides by 3
y = 40
6a+15+5a-10
11a+5 this is the answer
