Question

Solve. Problem attached.

Answer 1

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

Answer 2

Please explain

Answer 3

probably easiest start is to "cross multiply" don't forget parentheses
\[15\times 3=5(x+2)\] and work from there

Answer 4

alternatively you could note that \(\frac{3}{5}=\frac{9}{15}\) and solve
\[9=x+2\] in fact that might be easier
