The answer is add 35 and 52 and you will get 87 which was supposed to be the amount sold
Collect like terms
-3w - 7 w =5
Divide both sides by -10
-10w =5
w = -1/2
Angle E=130degrees because those two are congruent. Therefore if you 180-130 you'll get the other angle in the triangle with 70degrees and y. 180-130=50degrees. Then add 50 and 70. 50+70=120degrees. A triangle is supposed to have 180 degrees inside.
180-120=60degrees.
Therefore y=60degrees
