20(8x-2) = 12 (2x+4)

Răspuns :

Explicație pas cu pas:

[tex] \bf 20(8x - 2) = 12(2x + 4) \\ \\ \bf 160x - 40 = 24x + 48 \\ \\ \bf 160x - 24x = 48 + 40 \\ \\ \bf 136x = 88 \\ \\ \bf x = \frac{88}{136}^{(8} \implies \red{ \boxed{ \bf x = \frac{11}{17} } } [/tex]

Bună! ✨

[tex]20 ( 8 x - 2 ) = 12 ( 2 x + 4 ) \\ \\ 160x-40=12\left(2x+4\right) \\ \\ 160x-40=24x+48 \\ \\ 160x-40-24x=48 \\ \\ 136x-40=48 \\ \\ 136x=48+40 \\ \\ 136x=88 \\ \\ x=\frac{88}{136} \\ \\ \: \boxed{x=\frac{11}{17} }[/tex]
