We hates fractions
times everybody by 6x
6=x²-5x
minus 6 both sides
0=x²-5x-6
factor
what 2 numbers multiply toget -6 and add to get -5
-6 and 1
0=(x-6)(x+1)
set to zero
x-6=0
x=6
x+1=0
x=-1
x=6 or -1
Answer:
Step-by-step explanation:
Use substitution, y=3x+18 so -12x+4(3x+18)=-24. From here you can try to solve for x
-12x+12x+72=-24
The xs cancel, which leaves you with 72=-24
Since 72 cannot equal -24 there is no answer to this system of equations
Answer:
