Question

Resolva a seguinte equação : (urgente!!)

Answer 1

Resposta:

x=6

EXPLICAÇÃO:

43+(x)1=1211

x012x4,x,12

12x\times \left(\frac{3}{4}\right)+12=11x12x×(43)+12=11x

12\times \left(\frac{3}{4}\right)=9

\frac{12\times 3}{4}x+12=11x412×3x+12=11x

12336

\frac{36}{4}x+12=11x436x+12=11x

3649

9x+12=11x9x+12=11x

11x

9x+12-11x=09x+12−11x=0

9x-11x-2x

-2x+12=0−2x+12=0

12

-2x=-12−2x=−12

-2

x=\frac{-12}{-2}x=−2−12

-12-26

x=6x=6
