    s\[\frac{ x - 3 }{ 8 } =16\]

    Typo. The s means nothing.

    I'm not familiar with these ratios. 16/4? Or 16 = 4?

    \[\frac{ 16 }{ 4 }\]

    Since they're similar, you can set up a proportion. Make sure you keep the same triangle in the same fraction and the same sides in the same spot (numerator or denominator). \[\frac{ x-3 }{ 16 }=\frac{ 2.5 }{ 4 }\]Now, cross multiply:\[4(x-3)=16(2.5)\]\[4x-12=40\] Can you solve from here? :o)

    \[4x - 12 = 40\]\[4x = 40 + 12\]\[4x = 52\]\[4x / 4x = 52 / 4x\]\[x = 13\]
