4x + a million/2 (12x+2) = 3 a million.) You multiply 12x + 2 via a million/2 4x + 6x + a million = 3 2.) You upload 4x and 6x 10x + a million = 3 3.) You subtract a million from 3 10x - a million - a million 4.) You divide the two facets via 10 10x= 2 5.) Your answer is a million/5 or 0.2 10x/10 = 2/10 X= a million/5

8x + 12x + 2 = 6
20x = 4
x = 4/20
x = 1/5

10x+1=3
10x=2
x=1/5

4x + (1/2)(12x + 2) = 3
4x + (12x + 2)/2 = 3
4x + 6x + 1 = 3
10x = 3 - 1
10x = 2
x = 2/10
x = 1/5 (0.2)

8x+12x+2=6 multiply by 2
20x=4 add like terms
x = 1/5

4x+1/2(12x+2)=3

4x+6x+1=3
10x+1=3
10x+1-1=3-1
10x=2
x=2/10=1/5
2008-07-15 6:43 pm
4x +6x +1 =3

10x+1=3

10x = 2

X=1/5
