Let n=the number
2(n-6)=twice the sum of the number and -6:
-6(n+4)=-6 times the sum of the number and 4
And we are told that the above two quantities are equal. So our equation to solve is:
2(n-6)=-6(n+4) get rid of parens
2n-12=-6n-24 add 6n and also 12 to both sides
2n+6n-12+12=-6n+6n-24+12 collect like terms
8n=-12 divide both sides by n
n=-12/8=-3/2=-1.5--------------------------------the number
ck
2(-1.5-6)=-6(-1.5+4)
2(-7.5)=-6(2.5)
-15=-15
