Question

Solve this equation: y/9 + 5 = 0. A. y = 45 B. y = 5 C. y = –45 D. y = –5

Answer 1

Answer:

C.$y=-45$

Step-by-step explanation:

We are given that an expression

$\frac{y}{9}+5=0$

We have to find the value of y

$\frac{y}{9}+5=0$

Using subtractive property of equality

Subtractive property of equality : When a positive number goes from left side of equal to to right hand side of equal to then the sign changes into negative sign.

$\frac{y}{9}=-5$

Using multiplication property of equality then we get

$y=-5\times9$

$y=-45$

Hence, option C is true.

Answer 2

Y/9 +5 = 0   subtract from both sides 5 and will get 

y/9 +5 -5 = -5

y/9 = -5 multiple both sides by 9 and will get 

y = - 45  so choice C. is right sure
