Answer:
70.925 I believe
Step-by-step explanation:
Answer:
No, it isnt a solution
Step-by-step explanation:
Even though it works for one equation, it doesnt work on the other. You have to have the solution work for both equations so that it can be a true solution. Hope this helps you understand!
24 = -v/3 (first you multiply 3 to each side)
<u>×3 ×3</u>
<u />72 = -v (then you divide -1 from each side)
-72 = v<u><u /></u><u />
To find the number you would start by writing out the equation using x as the number. The equation would be x+2x=21. The first step to solve this equation would be to combine like terms, making the equation 3x=21. Finally, you would divide both sides by three, making your answer x=7.
