Question

solve 3x - 9 + x > 27

Answer 1

Start of by collecting like terms on the left side,

\[3x+x = 4x \implies 4x-9 > 2\]

now add 9 on both sides to get rid of it on the left,

\[4x>2+9 \implies 4x> 11\]

divide by 4,

\[x > \frac{ 11 }{ 4 }\]

Answer 2

Treat the > like an =. The goal is to isolate x, so I would add 9 to both sides of the equation to start out.

Answer 3

that answer isnt a choice

Answer 4

This will give you 3x+x=36

Combine like terms to get 4x=36.

Divide 36 by 4 to isolate x, so x=39.
