Question

Solve for y.... y/2-y3+y4=5/12​

Answer 1

Answer:

y= 1

Step-by-step explanation:

y/2 - y/3 + y/4 = 5/12

LCM of 2,3 and 4 is 12.

so,(6×y)/12 - (4×y)/12 + (3×y)/12 = 5/12

that is, 6y/12 - 4y/12 + 3y/12 = 5/12

that is, (6y-4y+3y)/12 = 5/12

that is, 5y = (12×5)/12 = 5

that is, y = 5/5 = 1

hence,y = 1

Answer 2

$\huge{\bf{\pink{Solution}}}$

$\frac{y}{2} - \frac{y}{3} + \frac{y}{4} = \frac{5}{12} \\ \\ \frac{3y - 2y}{6} + \frac{y}{4} = \frac{5}{12} \\ \\ \frac{y}{6} + \frac{y}{4} = \frac{5}{12} \\ \\ \frac{4y + 6y}{24} = \frac{5}{12} \\ \\ \frac{10y}{24} = \frac{5}{12} \\ \\ \frac{5y}{12} = \frac{5}{12} \\ \\ 5y = 5 \\ \\ y = 1$

it is the answer Pls make me as brainliest pls ☺

have a nice day ❤
