Answer:

Step-by-step explanation:
Let the angle between
and 150° be = b°
[ Forming a linear pair of angles]
Solving for
by subtracting both sides by 150.

∴ 
[Angle lying on a straight line add up to 180]
Plugging in 

Solving for
by
subtracting both sides by 80.

then dividing both sides by 2.

Answer:
<h2>
y = 4</h2>
Step-by-step explanation:
x + 2y = 10 ⇒ 2y - 10 = -x
-x + 4y = 14
2y - 10 + 4y = 14
6y = 24
y = 4
1/3 (3x+12)
1/3×3x+1/3×12
x+4
8 cause 88-64=24(you have to distribute)
