Answer:
Step-by-step explanation:
-4=2x+16
-16. -16
-20=2x
20/2=2x/2
10=x
4/5 is already simplified so its going to be 4/5 or .45

- What is the solution to the inequality -3x-42>3 ?


Add 42 to both sides.

Add 3 and 42 to get 45.

Divide both sides by -3. As -3 is <0, the inequality direction has changed.

Divide 45 by -3 to get -15.

Valid because 3 x 3 is 9 :))
