Answer:
2) y = x - 4
y = -x + 2
=> x - 4 = -x + 2
=> 2x = -6
=> x = -3
=> y = -3 - 4 = -7
3) y = 3x + 1
y = 5x - 3
=> 3x + 1 = 5x - 3
=> 2x = 4
=> x = 2
=> y = 3(2) + 1 = 7
4) 2x + y = 8 => y = -2x + 8
y = x - 7
=> -2x + 8 = x - 7
=> 3x = 15
=> x = 5
=> y = 5 - 7 = -2
Answer:
it must be number 1
I am sure about parallel side and 4 right angles
ANSWER:
x=5
ok so
2x+3=4x-7
+7 +7
2x+10=4x
-2x -2x
10=2x
--- ----
2 2
x= 5
