Question

Find the solution of the following equation:
Answer in 2 min.​

Answer 1

Answer:

If $\frac{15x - 12}{3} = 21 - 5x$ then x = 2.5

Step-by-step explanation:

Find the solution of the following equation

$\frac{15x - 12}{3} = 21 - 5x\\15x - 12 = 3 (21 -5x)\\15x -12 = 3(21) - 3(5x)\\15x - 12 = 63 - 15x\\15x + 15x = 63 + 12\\30x = 75\\x = \frac{75}{30} \\x = 2.5$

Answer 2

Answer:

The solution of the given equation is = 5/2

Step-by-step explanation:

We have to find the solution of the equation,

(15x - 12) /3 = 21 - 5x

=> (15x - 12) ÷3 = 21 - 5x

=> 15x -12 = 3×(21 - 5x)

=> 15x - 12 = 63 - 15x

=> 15x + 15x = 63 + 12

=> 30x = 75

=> x = 75/30

=> x = 25/10 = 5/2

So, the value of x is = 5/2

That is , the solution of the given equation is = 5/2
