Answer:
x = ![\frac{10}{1 + 2x}](https://tex.z-dn.net/?f=%5Cfrac%7B10%7D%7B1%20%2B%202x%7D)
Step-by-step explanation:
Let the number be x
x + 2x² = 10
Factorize x + 2x²
x(1 + 2x) = 10
Divide both sides by (1 + 2x)
x = ![\frac{10}{1 + 2x}](https://tex.z-dn.net/?f=%5Cfrac%7B10%7D%7B1%20%2B%202x%7D)
Good question let me see if I can figure it out
2/10 and 2/100 would be the fractions and 0.20 and 0.02 would be the decimals
(1)x+y=11 given
(2)x-y=5 given
x=5+y equality property of addition (add y to both sides of (2)
5+y+y=11 sub previous result in to (1)
2y=6 algebra and simplificatiuon
y=3 division property of equality (divide both sides by 2)
x=8 again sub previous into (1)
