Answer:
x=5
Step-by-step explanation:
4x+5=3x+10
All x values must go on the right so subtract 3x from both sides
4x+5=3x+10
-3x -3x
which gets you
x+5=10
Now subtract 5 from both sides to get the value of x
x+5=10
-5 -5
And you get
x=5

So all points on the line will satisfy both equations.
Hence infinitely many solutions
