Answer:
Number 6 is x=65 number 7 is x=-1
Step-by-step explanation:
I just did number 6 on another persons page but ill repeat it as best i can
You're going to set to X plus 2 = 3X -63 then you are going to subtract 2X from both sides which will leave you 2 equals X -63 and then you add 63 to both sides which will leave you x equals 65
Number 7
2X plus 20=6X plus 24
1st Subtract 2X from both sides which will leave you with 20 = 4X plus 24
2nd you're going to subtract 24 from both sides Which will leave you with negative 4 = 4X
Then you're going to divide both sides by 4 which will leave you with X equals negative one
