Answer:
Yes
Step-by-step explanation:
Given the system of equations
We want to determine if (2,5) is a solution of the system.
We can do this by substitution of the given point into the equations and see if it holds.
Given (x,y)=(2,5), x=2, y=5
<u>In the first equation</u>
y=2x+1
5=2(2)+1
5=5
Therefore, <u>the point (2,5) satisfies the first equation.</u>
<u>In the second equation</u>
Since our result (-3) is equal to the Right Hand Side, <u>the point also satisfies the second equation.</u>
<u />
Therefore, (2,5) is a solution of the system.
