Answer:
A ) ( 5 ,0 ) .
Step-by-step explanation:
Given : 2x + y = 10
y = x – 5.
To find : Use the substitution method to solve the system of equations.
Solution : We have given
2x + y = 10 -------(1)
y = x – 5---------(2).
Plug y = x -5 in equation 1
2x + x - 5 = 10 .
3x -5 = 10 .
On adding both sides by 5 .
3x = 10 + 5 .
3x = 15
On dividing by 3 both sides
x = 5 .
Now, plug x = 5 in equation 2
y = 5 -5
y= 0 .
( 5 ,0 )
Therefore, A ) ( 5 ,0 ) .
