Sagot :

[tex]5x + (6x - 5) + (3x + 10) = 360[/tex]

[tex]5x + 6x - 5 + 3x + 10 = 360[/tex]

[tex]11x - 5 + 3x + 10 = 360[/tex]

[tex]14x + 5 = 360[/tex]

[tex]14x = 360 - 5[/tex]

[tex]14x = 355[/tex]

[tex]x = 25.36[/tex]

__________________________

[tex] x = 25.36[/tex]

[tex]5x = 5 \times 25.36 = 126.8[/tex]

[tex]6x - 5 = 6 \times 25.36 - 5 = 147.16[/tex]

[tex]3x + 10 = 3 \times 25.36 + 10 = 86.08[/tex]
