I have no idea how to slove this 5x-5 =2×+97​
galina1969 [7]

Answer: x=34

Step-by-step explanation:

1. You subtract 2x from 5x on the other side to get rid of the 2x leaving you with 3x.

2. Then you add 5 to 97 to get rid of the -5, giving you 102 on the opposite side.

3. divide 102 by 3x giving you 34.

5x-5=2x+97

-2x     -2x

3x-5=97                                                                      <u><em>X=102</em></u>

   +5  +5

3x=102

x/3   102/3

HELP PLS ITS URGENT
marysya [2.9K]

Melanie: 15 years old

Kevin: 5 years old

Assume Kevin's present age is x.

That means that 3 years ago, his age would be x - 3.

Melanie's age would be 6(x - 3).

Same thing for 5 years into the future:

Kevin's age would be x + 5.

Melanie's age would be 2(x + 5).

The two equations we have here are:

\left \{ {{x + 5 = 2(x + 5)} \atop {x - 3 = 6(x - 3)}} \right.

By subtracting both equations, we are simplified to:

8 = -4x + 28

By solving the equation, we get x = 5.

That means that Kevin's current age is 5 years old.

Melanie's age could be calculated by substituting Kevins'.

6(x - 3) --> 6(5 - 3) --> 12

Since that was 3 years ago, you need to add 3 to 12 to get her current age.

12 + 3 = 15

Melanie's current age is 15 years old.
