Step-by-step explanation:
(x-3)-4(x+3)-5=0
(x−3)−4(x+3)−5=0
-4x+3
x-3-4x-12-5=0
x−3−4x−12−5=0
x-4x-3x
-3x-3-12-5=0
−3x−3−12−5=0
12-3-15
-3x-15-5=0
−3x−15−5=0
5-15-20
-3x-20=0
−3x−20=0
20
-3x=20
−3x=20
-3
x=\frac{20}{-3}
x=
−3
20
\frac{20}{-3}\approx -6.666666667
-\frac{20}{3}\approx -6.666666667
x=-\frac{20}{3}
x=−
3
20
