Question

x+4/13=x/11,atunci x este egal cu?​

Answer 1

$\mathbf{ \frac{x + 4}{13} = \frac{x}{11} }$

$\mathbf{11(x + 4) = 13x \Longleftrightarrow \: 11x + 44 = 13x }$

$\mathbf{11x - 13x = - 44}$

$\mathbf{ - 2x = - 44}$

$\mathbf{x = - 44 \div ( - 2) \Longrightarrow \: \boxed{\mathbf{x = 22}}}$

Sau daca te-ai referit la :

$\mathbf{x + \frac{4}{13} = \frac{x}{11} }$

$\mathbf{143x + 44 = 13x \Longleftrightarrow \: 143x - 13x = - 44}$

$\mathbf{130x = - 44 \Longrightarrow \: x = - \frac{44}{130} {}^{(2} = \:\boxed{\mathbf{ - \frac{22 }{65} }} }$

Bafta ! :)

Answer 2

Salut!

$\frac{x + 4}{13} = \frac{x}{11}$

$13 \times x = 11 \times x + 44$

$13x - 11x = 44$

$13x - 11x = 2x$

$2x = 44$

$x = 44 \div 2$

$x = 22$
