Simplify the expression.
3g- 9+ 11g - 21
The simplified expression is

g = -0.8571428571

Step-by-step explanation:

3g + -9 + 11g + 21 = 0

Reorder the terms:

-9 + 21 + 3g + 11g = 0

Combine like terms: -9 + 21 = 12

12 + 3g + 11g = 0

Combine like terms: 3g + 11g = 14g

12 + 14g = 0

Solving

12 + 14g = 0

Solving for variable 'g'.

Move all terms containing g to the left, all other terms to the right.

Add '-12' to each side of the equation.

12 + -12 + 14g = 0 + -12

Combine like terms: 12 + -12 = 0

0 + 14g = 0 + -12

14g = 0 + -12

Combine like terms: 0 + -12 = -12

14g = -12

Divide each side by '14'.

g = -0.8571428571

Simplifying

g = -0.8571428571

hello :

70y^8 + 30y^6 = 2 ( 35 y^8 + 15y^6)

the lenght is : 35 y^8

the width is : 15y^6

y=1/4x-4
