[tex] \frac{23}{x + 5} = \frac{115}{37.5} [/tex]
[tex]x + 5 = \frac{37.5 \times 23 }{115} [/tex]
[tex]x + 5 = \frac{862.5}{115} [/tex]
x+5= 7,5
x=7,5-5
x=2,5
[tex] \frac{4x - 5}{0.5} = \frac{36}{4.5} [/tex]
[tex]4x - 5 = \frac{36 \times 0.5}{4.5} [/tex]
[tex]4x - 5 = \frac{18}{4.5} [/tex]
4x-5= 4
4x= 4+5
4x= 9
[tex]x = \frac{9}{4} [/tex]
x= 2.25
Sper că te-am ajutat!
