Y=3×+7 y=×-9 what is the solution of the equation

2 answers:

7 0

Since both equations are equal to y you can just make them equal to each other, like this 3x + 7 = x - 9. From there isolate the varible x on one side so that the solution will be on the other side of the equation. I'll do the steps too for you.

3x + 7 = x - 9

2x + 7 = -9

2x = -16

x = -8

Hope this helps :)

The answer is -8 because you set the equations equal to each other and solve for x

Puis traveled one-quarter of the journey to his destination. He still has to cover 24km to reach the third-way mark. How many ki

sertanlavr [38]

Answer:

The distance Puis still have to travel to reach his destination is 72 km.

Step-by-step explanation:

The given parameters about Puis journey are

Distance covered by Puis = 1/4 of total distance

Distance remaining for Puis to complete the journey = 3/4 of the journey

Distance of Puis from the third-way (central) mark = 24 km

Therefore;

Distance from 1/4 of journey to 1/2 of journey = 24 km

Hence, 1/2 - 1/4 = 1/4 of the journey = 24 km

Which gives Total distance covered by Puis = 24 km

Total distance of the journey = 4 × 24 km = 96 km

The distance Puis still have to travel to reach his destination = 96 - 24 = 72 km.
