Question

-9=3x+6 what is the value of x?

Answer 1

Answer:

-5

Step-by-step explanation:

3x + 6 = -9

3x = -15

x = -5

Answer 2

Answer:

$\boxed{ \bold { \huge{ \boxed{ \sf{x = - 5}}}}}$

Step-by-step explanation:

$\sf{ - 9 = 3x + 6}$

Swap the sides of the equation

$\longrightarrow{ \sf{3x + 6 = - 9}}$

Move 6 to right hand side and change its sign

$\longrightarrow{ \sf{3x = - 9 - 6}}$

The negative integers are always added but possess the negative ( - ) sign

$\longrightarrow{ \sf{3x = - 15}}$

Divide both sides by 3

$\longrightarrow{ \sf{ \frac{3x}{3} = \frac{ - 15}{3} }}$

Calculate

$\longrightarrow{ \sf{x = - 5}}$

Hope I helped!
