First : Distributive Property
(1/9∙x)+(1/9∙18)
1/9x+18/9
(1/3∙2x)+(1/3∙3)
1/9x+2+2/3x+1=x+3
Second : Rearrange
1/9x+2/3x-x+3-2-1
Third : Solve! :D
-7/9x=0
7/9x=0
x=0
Answer:
Step-by-step explanation:
(x+y) = x² +2xy + y²
:::::
(x+y)(x-y) = x² - y²
no solution
12x - 42 - 3 = 12x - 21
12x - 45 = 12x - 21
-45 ≠ -21
