Answer:
x=2.9
Step-by-step explanation:
3(3x+9)= -5-2x ( distribute)
9x+27= -5-2x (add 2x) (subtract 27)
11x= 32 ( divide by 11)
x= 2.9
Add like terms. "Like terms" are those with the same constellation of variables.
.. terms with variable x: 5x +3x = (5 +3)x = 8x
.. terms with no variable: -9 -20 = -29
The simplified form is 8x -29.
