Question

What is the solution to the equation 3x+9-7x=2(x+6)

Answer 1

Answer:

x=-1

Step-by-step explanation:

hello :

3x+9-7x=2(x+6)

3x+9-7x=2x+12

3x-2x-7x=12-9

-6x = 6

x=6/-6 = -1

Answer 2

Answer:

x = - $\frac{1}{2}$

Step-by-step explanation:

Given

3x + 9 - 7x = 2(x + 6), that is

- 4x + 9 = 2x + 12 ( subtract 2x from both sides )

- 6x + 9 = 12 ( subtract 9 from both sides )

- 6x = 3 ( divide both sides by - 6 )

x = $\frac{3}{-6}$ = - $\frac{1}{2}$
