I do not know how to solve and graph linear systems such as:

x+y=2
-3x+4y=36

solve by graphing. X - 2y = 7, -5x + y = 10

First of all, draw the graphs on a suitable graph paper as accurately as you can. I suggest a range of 0 to 10 on the y-axis and -5 to 2 on the x-axis.

Where the two lines meet, give the coordinates of that point of intersection. That is the answer of your question. Note that the answer is in the form (x, y)

Draw your graphs. The solution is given by the point where they meet.

I do not know how to solve and graph linear systems such as: x+y=2 ; -3x+4y=36

Step one : solve the values of X and Y (x+y=2 ; so 3x+3y=6 ; while -3x+4y=36) Add together to solve.
Step two : draw graph using X and Y values.
Step three : measure resulting line to solve.
