Y=5x+7
3y-15x=21 a. No solition b. One solution c. Infinite
a. No solution
To find the solution, we can first rearrange the second equation:
3y - 15x = 21
3y = 15x + 21
y = 5x + 7
Now we can see that both equations are the same, which means they represent the same line. Since they have the same slope and y-intercept, they are parallel lines and will never intersect. Therefore, there is no solution.
