Question

Resolva a equação: 4x-10(x-1)-2.(x-2)=0

Answer 1

$4x-10*(x-1)-2*(x-2)=0 \\ 4x-(10x-10)-2*(x-2)=0 \\ 4x-10x+10-2*(x-2)=0 \\ -6x+10-2*(x-2)=0 \\ -6x+10-(2x-4)=0 \\ -6x+10-2x+4=0 \\ -8x+10-4=0 \\ -8x+14=0 \\ -8x=-14 \\ x=-14/-8 \\ x= \frac{-14}{-8} \\ x= \frac{14}{8} \\ x= \frac{7}{4} \\ x=1,75$
