Question

Alguien sabe las respuestas

- 8x + 17 = 10x -1

4x-8= -4(2x-3)+4

4 (x - 3) + 40 = 64 – 3 (x -2 )

(-7x)/3+1/2= (5x+2)/3


x/3+2= 2x/5+17/15

Answer 1

Resultado :
1. -8x -10x = -17-1
- 18x. = -18
x = -18/-18
x. = 1

2. Multiplicas el paréntesis por -4.
4x-8=-8x+12+4
4x-8=8x+12+4
16
4x+8x=16+8
12x=24
X=2

3. 4x+28=70-3x
4x-12+40=64-3x+6
4x+28=70-3x
4x+3x=70-28
7x=42
X=6


4. -14+3=2 (5x+2)
-14x+3=10x+4
-14x-10x=4-3
-24x=1
X= - 1/24


5. x/3+2=2x/t+17/15
5x+30=6x+17
5x-6x=17-30
-x= -13
x=13
