What is -3 - 9n= 42 i can’t be negative

If you were to correctly simplify this equation, the answer would be a negative.

The answer is: n = -5

Here's how I got my

Step 1: Add 3 to both sides. Which leaves us with

Step 2: Simplify to 45. Which leaves us with

Step 3: Divide both sides by -9. Which leaves us with

Step 4: Simplify , to get your answer, n = -5.

the system of inequalities is

step-by-step explanation:

step 1

find the equation of the dashed line

we have the points

(0,0) and (3,1)

the line passes through the origin, so, is a direct variation

find the slope

the equation of the dashed line is

the solution of the inequality a s the shaded area above the dashed line

therefore

the equation of the inequality a is

step 2

find the equation of the solid line

we have the points

(4,0) and (0,4)

find the slope

the equation of the solid line is

the solution of the inequality b s the shaded area below the solid line

therefore

the equation of the inequality b is

step 3

the system of inequalities is
