post an equation first.
2x+7y=29 x=37-8y
y=3x-4 y=-2x+1

x - 2y = -4 2x - y = 1 To solve this system of equations, I used matrices, and got x = 2 and y = 3.
2x - 5 = 11 2x = 11 + 5 2x = 16 2x /2 = 16 /2 x = 8
Use the substitution method to solve the system of equations. Enter your answer as an ordered pair.y = 2x + 5 x = 1
The solutions are: x = -2 and y = 4
3x-8y=-1 -2x+6y=1

How many solutions are there to the following system of equations?2x - y = 2-x + 5y = 3if this is your question,there is ONLY 1 way to solve it.
y=2x+12 7x+y=24 (as there is y in both equations you can assume that the equations are equal to each other, so substitute) 7x+2x+12=30 (solve) 9x=18 x=2 (substitute into the first equation to solve for y) y=(2x2)+12 y=16
2x+7y=29 x=37-8y
y=3x-4 y=-2x+1
x + y = 50 x - y = 16 --------------- (add the two equations to solve for x) 2x = 66 x = 33 then substitute x into one of the above equations to get y = 17
x = 4 and y = 0
Check your text book for how to solve it.
