$\huge\underline\mathtt\red{Answer}$

Given:-

15x - 12 3= 21 - 5x

15x−12 =21−5x

⠀

Solution :

By transporting the values, we will find the value of x.

⠀

15x - 12/3 = 21 - 5x

⟼ 3

15x−12

=21−5x

15x - 12 = 3(21 - 5x

⟼15x−12=3(21−5x)

⠀

15x - 12 = 63 - 15x

⟼15x−12=63−15

15x + 15x = 63 + 12

⟼15x+15x=63+12

30x = 75

⟼30x=75

⠀

x = 75/30

⟼x= 3075

x = 5/2

⟼x= 25

Hence, the value of x is 5/2.

Note :-

We have to find the value of X and subtract it with the solution.

Answer 2

Answer:

Given:

15x - 12 / 3 = 21 - 5x.

Answer:

Given, x -2 = 7

=> x – 2 + 2= 7 + 2 [Adding 2 both sides]

=> x = 9
