[tex] \large \tt{x + 3x + 4x = 200} \\ \large\tt{8x = 200} \\ \tt{ x = \large\frac{200}{8}} \\ \large\boxed{\blue{\tt{x = 25}}}[/tex]
[tex]\\[/tex]
Substitute the value of x to the proportions:
[tex] \large \: x = \blue{25}\\ \large3x = 3( \red{25}) \implies \red{75} \\ \large4x = 4( \purple{25}) \implies \boxed{\purple{100}}[/tex]
