Answer:
x=9, y=14
Step-by-step explanation:
2x+27+2x+27=90
4x+54=90
4x=36
x=9
4y-19 = y+23

Answer:(-x-1)(x-4)
Step-by-step explanation:

factor the equation (multiples of 4 are 1 and 4 and 2 and 2) 4-1=1 so the factor you want to use are 1 and 4
-1(x +1)(x-4) -- -4+1=3
distribute the -1 into the first factor
(-x-1)(x-4)
