Question

the root of the equation
2y=5(7-y)
​

Answer 1

Answer:

$2y = 5(7 - y)$

$2y = 35 - 5y$

$2y + 5y = 35$

$7y = 35$

$y = \frac{35}{7}$

$y = 5$

Answer 2

Answer: 5

Step-by-step explanation:

Rearrange terms

$2y=5(7-y)$

$2y = 5(-y+7)$

Distribute

$2y = 5(-y+7)$

$2y = -5y +35$

Add $5y$ to both sides

$2y=-5y+35\\2y+5y=-5y+35+5y$

simplify

combine like terms

$7y=35$

$y=5$
