Question

Y + 7 upon 3 equal to 1 + 3 Y - 2 upon 5​

Answer 1

y+7/3 = 1+3y-2/5

(Cross multiplying)

5y+35=3+9y-6

5y-9y=3-6-35

-4y=-38

y=-38/-4

y=9.5

Answer 2

The correct answer is "y = 9.5". Further explanation is given below.

Step-by-step explanation:

Given equation is:

$\frac{y+7}{3} = \frac{1+3y-2}{5}$

On solving the above equation, we get

$\frac{y+7}{3} = \frac{3y-1}{5}$

On applying cross-multiplication, we get

⇒  5(y+7) = 3(3y-1)

⇒  5y+35 = 9y-3

On subtracting "35" from both sides, we get

⇒  5y+35-35 = 9y-3-35

⇒  5y = 9y-38

on subtracting "9y" from both sides, we get

⇒  5y-9y = -38

⇒  -4y = -38

⇒  y = $\frac{-38}{-4}$

⇒  y = 9.5
