Question

Con su respuesta y comprobación
2k+1/4=37/20​

Answer 1

2k + 1/4 = 37/20

20(2k) + 20(1/4) = 20(37/20)

40k + 20/4 = (20)(37)/20

40k + 5 = 37

40k = 37 - 5

40k = 32

k = 32/40

k = 4/5

Comprobación

2(4/5) + 1/4 = 37/20

8/5 + 1/4 = 37/20

(8)(4)+(5)(1)/(5)(4) = 37/20

32+5/20 = 37/20

37/20 = 37/20
