-2n-24=-8(2n-4) Multiply both sides by -1 2n+24=8(2n-4) Distribute the right side 2n+24=16n-32 Subtract 2n from both sides 24=14n-32 Add 32 to both sides 56=14n Divide 14 from both sides n=4
-2n-24=-8 (2n-4) Simplify Multiply 2n and -4 by -8 -2n-24=-16n+32 A negative ×negative =positive this is why 32 becomes positive A negative × a positive= negative this is why 16 becomes negative Now add both sides by 24 -2n= -16n+56 Now add 16n to both sides 14n= 56 Divide both sides by 14 N= 4 Hope that helps let me know if you need more help understanding:)
