x = -1.2, y = -3
-5x+50 = 25 -5x = 25-50 -5x = -25 x = 5
(5x800)+(5x20)+(5x3)=4000+100+15=4115
Since 5x is a factor of both terms, divide it. 5x3 + 5x = 5x(x2 + 1)

x = -1.2, y = -3
5x3 = 320 x3 = 320/5 = 64 So x = cuberoot(64) = 4
-5x+50 = 25 -5x = 25-50 -5x = -25 x = 5
(5x800)+(5x20)+(5x3)=4000+100+15=4115
The GCF is 5x
x=35
