Answer:
x=-7
Step-by-step explanation:
Since you are solving for x, you need to work backwards. Add 2 to both sides: -2 and 2 cancel out, and 19 plus 2 is 21. Isolate the x by dividing both sides by -3. -3 cancels out, and 21 divided by -3 is -7.
Answer:
-7
Step-by-step explanation
−2−3x=19
−2+−3x=19
−3x−2=19
Step 2: Add 2 to both sides.
−3x−2+2=19+2
−3x=21
Step 3: Divide both sides by -3.
−3x
−3
=
21
−3
x=−7
