15 ‒ 5x = 6x + 3 – 2x
LenKa [72]

Answer:

x = 4/3

Step-by-step explanation:

15 - 5x = 6x + 3 - 2x

In this kind of equation, we try to seperate the x's and the numbers.

So we add 5x to both sides and subtract 3 from both sides to seperate these values

15 - 3 - 5x + 5x = 6x + 3 - 3 - 2x + 5x

=> 12 = 9x

=> 12/9 = x

=> 4/3 = x

=> x = 4/3

To check, we can plug this in.

15 - 5(4/3) = 6(4/3) + 3 - 2(4/3)

15 - 20/3 = 24/3 + 3 - 8/3

45/3 - 20/3 = 24/3 + 9/3 - 8/3

25/3 = 25/3

So our answer works.
