Question

What is the solution to the equation 3 (2 x + 5) = 3 x + 4 x

Answer 1

Answer:

x = 5

Step-by-step explanation:

$3(2x + 5) = 3x + 4x \\ => 6x + 15 = 7x \\ = > 15 = 7x - 6x \\ = > 15 = x$

Answer 2

Answer:

x = 15

Step-by-step explanation:

3 (2x + 5) = 3x + 4x

6x  + 15 = 3x + 4x

6x - 3x - 4x = - 15

- x = - 15

x = 15
