Question

Resolver: x(x-2)/2 - (x-4) (x-7)/2=22​

Answer 1

Respuesta:

x=8

Explicación paso a paso:

x(x-2)2/-(x-4) (x-7)/2 =22

x(x-2) x2/2 - (x -4) (x-7)/2 =22x2

x(x-2) - (x - 4) (x-7) = 22x2

x² - 2x - x² + 4x + 7x - 28 =22x2

-2x + 4x + 7x - 28 =44

-2x + 4x + 7x =44 + 28

9x = 44 + 28

9x = 72

x= 72÷9

x =8
