1.
6(14  3x) +20x=90
8418x+20x = 90
84+2x = 90
(84+2x)84 = 9084
84+2x84 = 6
8484+2x = 6
2x = 6
(2x)/2 = 6/2
x = 3
2.
2/3x +15 = 1/2x +4
I assume that you mean
(2/3)x +15 = (1/2)x +4
[(2/3)x +15](1/2)x15 = [(1/2)x+4](1/2)x15
(2/3)x(1/2)x = 11
(2/3)x*6(1/2)x*6 = 11*6
4x3x = 66
x = 66
3.
2.9n + 1.7 = 3.5 + 2.3n
(2.9n+1.7)2.3n1.7 = (3.5+2.3n)2.3n1.7
2.9n2.3n+1.71.7 = 2.3n2.3n+3.51.7
0.6n = 1.8
(0.6n)/0.6 = 1.8/0.6
n = 1.8/0.6
n = (1.8*10)/(0.6*10)
n = 18/6
n = 3
HOPE THIS HELPS.

1]
6*146*3x+20x=8418x+20x=90
this implies 2x=9084=6
this in turn implies 2x=6
hence x=6\2=3
therefore x=3
2]
2\3x+15=1\2x+4
shifting places n getting all "x"terms on one side of the equation we get
2\3x1\2x=415
take lcm of 3x and 2x
it is 6x
so 43\6x=11
1\6x=11
6x=1\11
x=1\11*6
x=1\66
3]
2.9n2.3n=3.51.7{this we got after shifting places on either side of equal to sign}
after that
0.2n=2.5
n=2.5\0.2
hence n=12.5
that's it dude,did you get me,the answers are correct

Thu, 04 Jun 2009 07:26:16 +0000
1. 6(14  3x) +20x=90
6*14  6*3x + 20x = 90, distributive property
84  18x + 20x = 90
84 + 2x = 90, combine like terms
2x = 6, additive inverse on both sides
x = 3, divide by 2
2. 2/3x +15 = 1/2x +4
2/3x  1/2x + 15 = 1/2x  1/2x + 4
2/3x  1/2x + 15 = 4
2/3x  1/2x + 15  15 = 4  15
2/3x  1/2x = 11
4/6x  3/6x = 11, common denominator
1/6x = 11
x = 11 * 6 = 66
3. 2.9n + 1.7 = 3.5 + 2.3n
29n + 17 = 35 + 23n, multiplied entire equation by 10
29n  23n + 17 = 35 + 23n  23n
29n  23n + 17 = 35
29n  23n + 17  17 = 35  17
29n  23n = 35  17
6n = 18
n = 3

1. Distribute the 6, so you get 84  18x + 20x = 90
then combine like terms 18x + 20x = 90  84
so 2x = 6
and x = 3
2. Multiply everything by 6, so you get 4x + 90 = 3x + 24
then combine like terms so you have 4x  3x = 24  90
so x = 66
3. Combine like terms: 2.9n  2.3n = 3.5  1.7
.6n = 1.8
n = 3

2x = 6
x = 3

2/3x +15 = 1/2x +4 # multiply with 6
