Answer:
[tex]66\frac{2}{3}[/tex]
Step-by-step explanation:
[tex]\frac{3x}{5+5}=20\\\mathrm{Multiply\:both\:sides\:by\:}10\\\frac{10\cdot \:3x}{5+5}=20\cdot \:10\\Simplify\\3x=200\\\mathrm{Divide\:both\:sides\:by\:}3\\\frac{3x}{3}=\frac{200}{3}\\Simplify\\x=\frac{200}{3}[/tex]
[tex]66\frac{2}{3}[/tex]
Answer:
x = 5
Step-by-step explanation:
3x/5+5=20
-5 -5
(.5)3x/5 = 15(.5). (multiply both sides by 5, we got it from the /5)
15x(/15) = 75(/15) ( divide both side by 15, we got it from the 15x)
x = 5
