X = 1st integer, y = 2nd integer, z = 3rd integer

y = 2x
z = 2y......z = 2(2x)...z = 4x

y = x + 17
2x = x + 17
2x - x = 17
x = 17

y = 2x
y = 2(17)
y = 34

z = 4x
z = 4(17)
z = 68

and the sum would be : 17 + 34 + 68 = 119

X/19 &lt; -7<br> Inqualities
Hitman42 [59]

Because 19 is being divided, you have to do the opposite. What's the opposite of division? Multiplication. So multiply 19 to -7, then get rid of the 19 on the x's side(cuz it was cancelled out). Now you should have x<-133. In case you don't know, positive times negative equals negative, but negative times negative equals positive.

hope it helps

solmaris [256]
Y = 2x + 50, 

It's easier to look at the first set of numbers and then make a formula from there. so we need x to be zero and y to be 50, which is why the formula listed works.
