Question

Qual o valor de x na equação 2x/3 -x/5= 6(x-2) é: A-160/73B-120/53C-180/83D-140/63E-100/43

Answer 1

2x/3-x/5= 6.(x-2)     3,5=15 MMC
2x/3- x/5= 6x-12
10x - 3x= 90x - 180
7x - 90x= -180
-83x = -180    -(1)
180/83

Answer 2

2x/3 -x/5= 6(x-2)

5 ⠂2x - 3x = 90 (x-2)

10x - 3x = 90 (x-2)

7x = 90 (x-2)

7x - 90x = - 180

-83x = -180

x = -180/-83

x = 180/83

Espero ter ajudado !!
