Hello!
Judging by the question you have provided I have figured that the best way to go about finding the solution is by using the distributive property!
This means you will want to distribute the y = -3 into the 2y+7-4y-10 equation.
However, the first step you should take is to simplify the equations.
After simplifying the equations you should come out with the new equation being -2y-3.
You now want to distribute the y=-3 into the equation!
You should get -2(-3)-3. Now solve!
The answer you get should be 3!
Hope this helped!

incoorect Step-by-step explanation:
Supplementary Angles two angles that sum up to 180°
the other two sides are that and the other side is 70
Just work with it as seperate triangles and then add them up.
Answer:
a°=79°[alternate angles]
c°=83°[alternate angle]
a° +d°=180°[straight angle]
79°+d°=180
or,d°=180-79
so,d°=101°
Now,
b°+c°=170°[sum of straight angle]
b°+83°=180°
b°=180°-83°
so,b°=97°
