Graphing Quadratic and Linear Systems On the set of axes below, solve the following system of equations graphically and state the coordinates of all points in the solution set.
y=-x^2+2x+4
y=−x
2
+2x+4
2x-2y=4
2x−2y=4

2(10 - 13x) + 9x = -34x + 6020 - 26x + 9x = -34x + distributive property-17x = -34x + subtraction property (subtracted 20 from both sides)17x = addition property (added 34x to both sides)x = 40/ division property (divided both sides by 17)

The additive identity is 0 because when you add 0 to a number, you get the identical number as an answer.a + 0 = a

1/x-1+3/x-1=1
x is -1.333
