Solve:
Identify the x that is multiplied to each number in the fraction will have a total of 48.
[tex] \implies \sf \large2 \: : \: 4[/tex]
[tex] \implies \sf \large2x + 4x = 48[/tex]
[tex] \implies \sf \large6x = 48[/tex]
[tex] \implies \sf \large \frac{ \cancel6x}{ \cancel6} = \frac{48}{6} \\ [/tex]
[tex] \implies \sf \large \therefore \: x = 8[/tex]
[tex] \: [/tex]
Use 8 as the value of x to check and find how many doors and windows are there.
[tex]\implies \sf \large2(8) + 4(8) = 48[/tex]
[tex]\implies \sf \large16 + 32 = 48[/tex]
[tex]\implies \sf \large48= 48 \rightarrow \tt \green{true}[/tex]
[tex] \: [/tex]
Final Answer:
[tex] \sf \large \implies \huge \orange{16 \: doors}[/tex]
[tex]\sf \large \implies \huge \orange{32 \: windows}[/tex]
