How old is Samuel? (answer)

He's 22 correct? If you divide his age by 2 (the only even prime number) and add four, you get 15 which is the  LCM of 3 and 5

-9x - 13 = -103 (answer)

Hi again Kevin... same process for this question. You want to work to get the x by itself to solve the equation. Start by adding 13 to both sides and remember -103 PLUS 13 = -90... so you get -9x = -90 Next, divide both sides by -9 and you get x = 10

144 = -12(x+5) (answer)

First, you'll want to distribute the -12 across the parentheses... that will make it 144 = -12x - 60  Second, get the x by itself by adding 60 to both side... that'll make it 204 = -12x Last, divide both sides by -12 ... that'll make it -17 = x
