Answer:
(2,1)
Step-by-step explanation:
3x+y = 7
-2x +y = -3
Solve the second equation for y by adding 2x to each side
-2x+2x +y = -3+2x
y = -3 +2x
Substitute into the first equation
3x+ (-3+2x) = 7
Combine like terms
5x -3 = 7
Add 3 to each side
5x-3+3 = 7+3
5x = 10
Divide by 5
5x/5 = 10/5
x=2
Now we need to solve for y
y = -3 +2x
y = -3 +2(2)
y = -3+4
y =1
x - 3y =2
2x+ y =11 | *3
x - 3y = 2
6x +3y=33
--------------
7x =35
x=35:7
x=5
x-3y=2
5-3y=2
3y=5-2
3y=3
y=1
Answer:
point "PQ", points "P" & "Q", point "QP".
i'm not really understanding this question
Step-by-step explanation:
