Question

Resolva esta questão:

Answer 1

Fazendo mmc de 10,5,2

10,5,2|2
5,5,1|5
1,1,1  2.5=10

$\frac{1-3x}{10}-1= \frac{3}{5}- \frac{2-x}{2} - mmc\\ \\ \frac{1-3x-10}{10}= \frac{6-10-5x}{10} \\ \\ -3x-9=-5x-4 \\ \\ -3x+5x=-4+9 \\ \\ 2x=5 \\ \\ x=5/2$

Answer 2

1- 3x / 10 -1=3/5 -2-x/2
1-3x-10=6-5(2-x)/10 
1-3x-10=6-10-5x
-3x+5x=6-10+10-1
-2x=-4+9
-2x=-5 .(-1)
2x=5
x =5/2
