Answer:
The answer is y = 1/2
Step-by-step explanation:
-20y + 15 = 2 - 16y + 11 <----This is the original problem.
-20y + 15 = 13 - 16y <----- Use the commutative property and addition.
-20y + 15 = 16y -13 <-----Use commutative property.
-20y + 15 - 15 = 16y - 13 - 15 <----- Subtract 15 from both sides.
-20y = 16y - 2 <----- Simplify
-20y + 16y = 16y - 2 + 16y <------Add 16y to both sides.
-4y = -2 <---- Simplify
-4y/-4 = -2/-4 <---- Divide both sides by -4
y = 1/2
