The answer would be two and nineteen
Simplify. Combine like terms
7y - 3y = 4y
-12 + 9 = -3
----------------------------------------------------------------------------------------------------------------
4y - 3 = 0
Isolate the y. Note the equal sign. What you do to one side, you do to the other side. Do the opposite of PEMDAS.
4y - 3 (+3) = 0 (+3)
4y = 3
4y/4 = 3/4
y = 3/4
-----------------------------------------------------------------------------------------------------------------
y = 3/4 is your answer

2x+3+51=4x+8 ( external angle =the sum of two opposite internal angles)
2x+54=4x+8
46=2x
x=23
4x+8=92+8=100 degrees
2x+3=46+3=49 degrees
