Your inequations form the boundaries of the figure.
So change the < or > to an equal sign, then solve them in pairs.
You should get 3 sets of intersection points.
Solve the pairs of equations just like you did #1.
ok im stuck after this:
y = x + 2
x + y = 6
y = -2
I will do number one only.
We have this:
(1)Find x in the solution of the system 3x + y = 2 and 2x -3y = 16.
Your choice = (A)
We have a system of linear equations in two variables.
Here are the two equations:
3x + y = 2...Equations A
2x -3y = 16...Equation B
I will first isolate y in Equation A.
3x + y = 2
y = -3x + 2....I will plug the quantity (-3x + 2) in Equation B to find the value of x.
2x - 3y = 16
2x - 3(-3x + 2) = 16
2x + 9x - 6 = 16
11x - 6 = 16
11x = 16 + 6
11x = 22
x = 22/11
x = 2
Your choice is correct!
