-5x+3y=-6
9x-4y=1
try adding them together and get
9x-5x+3x-4y=1-6
4x-y=-5
multiply the equation by 3
12x-3y=-15
add this euation to -5x+3y=-6 and get
12x-5x+3y-3y=-6-15
7x=-21
divide both sides by 7
x=-3
subsitute x=-3 for x in any equation
9x-4y=1
9(3)-4y=1
27-4y=1
-4y=-26
divide both sides by -4
y=6 and 2/4 or 6.5
x=-3
y=6.5
The formula of area is length x width
so if the area is already found , 54 divided by 9 is 6.
The other side of the rectangle is 6 units
for a picture you can just draw a rectangle and label the side 9 and 6 units lol

A triangle has <u>NO</u> parrallel lines. It cannot. Think of a triangle. IF it had a parralell line(s), it would not have 3 sides.

Hope this helps!
