Answer: x=-2, y=2
Step-by-step explanation:
(SUBSTITUTION)
= 4x+4-x=2
x=-2
3y=4 x (-2)
y= 2
Spencer would be the correct one because it's easier to keep your variables positive when trying to solve. Therefore, in order to keep the variable positive, one would have to add 4x to both sides.
Given the fact that AB≈AD, then 35 is also the angle measure of ADB. The sum of the angles of a triangle =180. 35+35=70. 180-70=110
X=110°
