Question

? 4/3m +2/5m - 7/4m= 2​

Answer 1

Explicación paso a paso:

4m/3 + 2m/5 - 7m/4 =2

MCD(3, 5 4) =3x5x4=60

4m(20)/60 + 2m(12)/60 - 7m(15)/60 = 2

80m/60 + 24m/60 - 105m/60 = 2

104m/60 - 105/60 = 2

- m/60 = 2

- m = 2(60)

- m = 120

m = 120/ - 1

m = - 120

Comprobación

4(- 120)/3 + 2(- 120)/5 - 7(- 120))4 = 2

4(- 40) + 2(- 24) - 7(-30) = 2

- 160 - 48 + 210 = 2

- 208 + 210 = 2

2 = 2
