Y = x + 4
y = 3x

 3x = x + 4
<u>- x  - x        </u>
 <u>2x</u> = <u>4</u>
  2     2
   x = 2
y = x + 4
y = 2 + 4
y = 6
(x, y) = (2, 6)

You just do 
3x=x+4
subtract x from both sides
2x=4
divide 2 from both sides
x=2
y=2+4
y=6
(x,y)= (2,6)

What is this please help I need this completed
Arturiano [62]

Answer:

angles 3 and 4 both equal a 90 degree angle or bisect a 90 degree angle.

angle 5 is 44-degrees because it is complementary or vertical to the 44 degree angle.

x=32 because it is on the same line as the 44-degree angle and a line is 180 so 180-44=136 and to get the rest of x you would do the equation backwards so 136 divided by 4 is 34 and 36-2=32

angle a is 136 described above.

angle b, because it is on the same line as the 46 degree angle is 180-46=134

now im pooped :(
