2x+%2B+7+%3E+x+%2B+12

2x+-x+%3E+12-7
x+%3E+5
the solution set is { x|x+%3E+5}

2x%2B7%3Ex%2B12 Start with the given inequality.


2x%3Ex%2B12-7 Subtract 7 from both sides.


2x-x%3E12-7 Subtract x from both sides.


x%3E12-7 Combine like terms on the left side.


x%3E5 Combine like terms on the right side.

Answer:

So the solution is x%3E5


the solution set is { x | x > 5 }
