x+4/13=x/11,atunci x este egal cu?​

Răspuns :

[tex]\mathbf{ \frac{x + 4}{13} = \frac{x}{11} }[/tex]

[tex]\mathbf{11(x + 4) = 13x \Longleftrightarrow \: 11x + 44 = 13x }[/tex]

[tex]\mathbf{11x - 13x = - 44}[/tex]

[tex]\mathbf{ - 2x = - 44}[/tex]

[tex]\mathbf{x = - 44 \div ( - 2) \Longrightarrow \: \boxed{\mathbf{x = 22}}}[/tex]

Sau daca te-ai referit la :

[tex]\mathbf{x + \frac{4}{13} = \frac{x}{11} }[/tex]

[tex]\mathbf{143x + 44 = 13x \Longleftrightarrow \: 143x - 13x = - 44}[/tex]

[tex]\mathbf{130x = - 44 \Longrightarrow \: x = - \frac{44}{130} {}^{(2} = \:\boxed{\mathbf{ - \frac{22 }{65} }} }[/tex]

Bafta ! :)

Salut!

[tex] \frac{x + 4}{13} = \frac{x}{11} [/tex]

[tex]13 \times x = 11 \times x + 44[/tex]

[tex]13x - 11x = 44[/tex]

[tex]13x - 11x = 2x[/tex]

[tex]2x = 44[/tex]

[tex]x = 44 \div 2[/tex]

[tex]x = 22[/tex]
