Answer :
Multiply the first equation by five to yield, 15x + 5y = 45. Add this equation to the second equation from the given,
15x + 5y = 45
+ 3x - 5y = 15
The answer would be 18x = 60. The value of x is 10/3. Therefore, the answer to this item is letter A.
15x + 5y = 45
+ 3x - 5y = 15
The answer would be 18x = 60. The value of x is 10/3. Therefore, the answer to this item is letter A.
Answer:
Option A. is the correct option.
Step-by-step explanation:
Two equations are 3x + y = 9 ------------(1)
and 3x - 5y = 15 ----------(2)
we have to calculate the value of x common for both.
We multiply equation 1 by 5 and add it to equation 2
15x + 5y = 45
3x - 5y = 15___
18x = 60
x = [tex]\frac{60}{18}=\frac{10}{3}[/tex]
Therefore option A. [tex]x=\frac{10}{3}[/tex] is the answer.
