Question

P) x-3/4 - 2x-1/5=5 ?

Q) x-1/2 +x-3/3 =6?

Pra manhã gente

Answer 1

P) x -3/4 -2x - 1/5 =5
x/20 - 2x/20 - 1/20 = 5/20
20x - 15 - 40x - 4 = 100
20x -40x = 100 + 15 +4
-20x = 119 ( - 1 )
20x = - 119
x = - 119/20
Q) x - 1/2 + x - 3/3 = 6
x/6 - 1/6 + x/6 - 3/6 = 6/6
6x - 3 + 6x - 6 = 36
6x + 6x = 36 + 3 + 6
12x = 45
x = 45/12 simplificando por 3 = 15/4
