Question

Y + 7 upon 3 is equal to 1 + Y​

Answer 1

Answer:

2

Step-by-step explanation:

y+7/3=1+y

by cross multiplication

3+3y=y+7

2y=4

y=2

Answer 2

The correct answer is "y = 2". Further explanation is given below.

Step-by-step explanation:

According to the question,

Given equation is:

$\frac{y+7}{3} = 1+y$

On applying cross-multiplication, we get

⇒  y+7 = 3(1+y)

⇒  y+7 = 3+3y

On subtracting "7" from both sides, we get

⇒  y+7-7 = 3+3y-7

⇒  y = 3y-4

On subtracting "3y" from both sides, we get

⇒  y-3y = 3y-4-3y

⇒  -2y = -4

⇒  y = $\frac{-4}{-2}$

⇒  y = 2
