Question

x/5+1=x/4+3/2

Me ajudem please

Answer 1

X/5 + 1 = x/4 + 3/2

MMC = 20

4x + 20 = 5x + 30

X = - 10

Answer 2

X/5+1=x/4+3/2
X/5 - x/4 = 3/2 - 1
Mmc (5,4,2)= 20
5,4,2: 2
5,2,1: 2
5,1,1: 5
1,1,1
= 2.2.5
= 4.5
= 20

(4x - 5x)/20 = (10.3 - 20.1)/20
- x = 30 - 20
- x = 10 (-1)
x = - 10

R.: x = - 10
