The graph below shows this system of linear equations.

anonymous · Answer

What is the solution to the system of linear equations?

 (4, 4)

 (4, 5)

 (0, -3)

 (0, 1)

anonymous · Answer

The solution is the point of intersection on the graph. Do you see it?

anonymous · Answer

That's for question 2

anonymous · Answer

you can use elimination to solve it ?

anonymous · Answer

The equations fit the picture you've given. You can use elimination or substitution. Probably substitution is easiest for this problem since you've got y= something already.
To solve:
x+1=2x-3

Get the x values on one side and the numbers on the other.

anonymous · Answer

x+1=2x-3
1+3=2x-x
4=x
Since you now know x, substitute 4 into the equations above. You'll find y.

anonymous · Answer

4+1=y                   2(4)-3=y
5=y                         8-3=y
                                  5=y     solution is (4,5)

Its unnecessary to solve using the elimination process.. just look at when both lines intersect. (4,5) .. they're already in slope intercept form.
