Question

resolver ecuaciones

2 x -7 = 5 x +2
3 + 4 x = 4x -5
-3 x + 6 = x -10
5x -2x +1 = x -11
x + 2 x -2 = 3x -2
x + 8 = 2x -8 + 3x
6x +7 -2x = - x -8
-9 -7x = 6 -2x -10
-4x + 3 -7x = -9 - 8x

Answer 1

2 x -7 = 5 x +2
-7-2=5x-2x
-9=3x
x=-3

3 + 4 x = 4x -5
4x-4x=-5-3
0=-8 (?)

-3 x + 6 = x -10
6+10=x+3x
16=4x
x=4

5x -2x +1 = x -11
5x-2x-x=-11-1
2x=-12
x=-6

x + 2 x -2 = 3x -2
3x-3x=-2+2
0=0

x + 8 = 2x -8 + 3x
8+8=5x-x
16=4x
x=4

6x +7 -2x = - x -8
4x+x= -8-7
5x=-15
x=-3

-9 -7x = 6 -2x -10
-9 -6 +10= -2x +7x
-5=5x
x= -1

-4x + 3 -7x = -9 - 8x
3 +9= -8x +4x +7x
12 = 3x
x=4

Espero te sirva!.
