Question

solve

Answer 1

\[\frac{ x+2 }{ 15 } + \frac{ 3-x }{ 5 }=\frac{ 2 }{ 3 }\]

Answer 2

First you need to add the two terms on the left hand side by using a common denominator. A good choice for a common denominator would be 15. Can you do that step?

Answer 3

im not really sure how to do that... i know that for the denominator I should probably multiply 5 times 3 but then...

Answer 4

Answer 5

\[\frac{x+2}{15}+\frac{3-x}{5}=\frac{x+2+3(3-x)}{15}=\frac{2}{3}\]
Now you need to simplify the numerator x + 2 + 3(3 - x)

Answer 6

Move the 2/3 to the LHS, combine the resulting terms and simplify.\[\frac{1}{15} (1-2 x)=0\]\[x=\frac{1}{2} \]
