Question

Solutia ecuatiei x+1supra4=5supra 12

Answer 1

x + 1 / 4 = 5 / 12

x = 5 / 12 - 1 / 4

x = 5 / 12 - 3 / 12

x = 2 / 12 = 1 / 6

Verific: 1 / 6 + 1 / 4 = 2 / 12 + 3 / 12 = 5 / 12

Answer 2

x+1/4=5/12 - aducem la acelasi numitor....12

12x/12+3/12=5/12 - eliminam numitorul prin inmultire cu 12

12x+3=5

12x=5-3

12x=2

x=2/12 - simplificam cu 2

x=1/6
