Answer:
n - (-6) < 9
n < 3
Step-by-step explanation:
When setting up an inequality, using the key words from the problem will help. The word 'difference' would indicate subtraction and 'less than' would be the '<' inequality sign. Since the expression is 'the difference of a number and -6', we write:
n - (-6) < 9
Whenever we subtract a negative number, we change both signs to positive:
n + 6 < 9
Using inverse operations to solve: n + 6 - 6 < 9 - 6
n < 3

Answer:
x = 6/3y+1
Step-by-step explanation:
x+3xy=6
Step 1: Factor out variable x.
x(3y+1)=6
Step 2: Divide both sides by 3y+1.
x(3y+1) / 3y+1
so x = 6/3y+1
