Question

Solve and check the equation:2y+5/y+4=1​

Answer 1

Answer:

We have, (2y + 5) / (y + 4) = 1 Let us perform cross-multiplication we get, 2y + 5 = y + 4 2y – y = 4 – 5 y = -1 Now let us verify the given equation, (2y + 5) / (y + 4) = 1 By substituting the value of ‘y’ we get, (2(-1) + 5) / (-1 + 4) = 1 (-2+5) / 3 = 1 3/3 = 1 1 = 1

Answer 2

Answer: y = -1

Step-by-step explanation:

2y+5/y+4 = 1

2y + 5 = y + 4

2y - y = 4-5

y = -1

Checking :

LHS = 2(-1) + 5/ (-1) + 4

       = -2 + 5/-1 + 4

       = 3/3

       = 1 = RHS
