✔ 最佳答案
8-10x-5=-3+6x+4
-10x-6x = -8-3+4
-16x=-7
x=7/16
8 - 5(2x + 1) = -3(1 - 2x) + 4
Expand the equation,
8 - 10x - 5 = -3 + 6x + 4
3 - 10x = 6x + 1
16x = 2
x = 2/16 = 1/8
Thus x = 1/8.
Hope this helps!
8 -10x - 5 = -3 + 6x + 4
3 - 10x = 1 + 6x
2 = 16X
x = 1/8
8 - 10x - 5 = -3 + 6x + 4
2 = 16x
x = 1/8
what does the comma mean? -2 < 3 - ok ? 8 subtract 3 from the two area: -2 - 3 < 3 - ok - 3 ? 8 - 3 -5 < -ok ? 5 multiply all sides by skill of -a million so the -ok is helpful. in doing this, the signs and indications replace: 5 > ok ? -5
8 - 5(2x + 1) = -3(1 - 2x) + 4
8 - 5*2x - 5*1 = -3*1 + 3*2x + 4
8 - 10x - 5 = -3 + 6x + 4
-6x - 10x = -3 - 8 + 5 + 4
-16x = -2
x = -2/-16
x = 1/8 (0.125)
8 - 10x - 5 = - 3 + 6x + 4
2 = 16 x
x = 1 / 8
8-10X+1=-3+6X+4
10X-6X=3+4+8-1
4X=14
X=14\4
X=3.5
hey this is easy.this is algebra so i am solving it in that way.
soln:
8-10x-5 = -3+6x+4
8-5+3-4 = 10x-6x
2 = 4x
x = 2
let me explain u how i got this. first of all u solve the brackets. then u combine the like terms n then evalute the expression n so u ll get the ans. which is 2.
i liv in dar so i m bieng taught this way....
just ask som1 else to make sure the ans. is right.
8-5 (2X+1) =3(2X+1) = 6X + 3
-3 (1-2X) + 4 = -3 +6X +4 = 1 +6x
6x+3=1+6x
6x +2 = 6x
( i dunno)
