You can skip 4 in that equation and you'll be left with 2x+12=0, which gives you 2x=-12 and finally, x=-6
You have to subtract 6y from both sides or subtract 7y from both sides(if you wanted to have a negative).
Answer:
D
Step-by-step explanation:
The other choices are wrong.
It's -1 because if you set -3 to x-1, you get x=-2.
2(-2)+3 would get you -1.
Answer: 110 degrees
------------------------------------------------------------------
Angle 2 is supplementary with angle 1, as they form a straight angle
This means the two angles add to 180 degrees
(angle 1) + (angle 2) = 180
(70) + (angle 2) = 180
angle 2 = 180 - 70
angle 2 = 110 degrees
