ayuda de nuevo :(
1. 5X-7+2X=4X+5
2. 5X-2X-4=X+7-5
3. X-(2X+1)=8-(3X+3)
4. 2(X+1)-5=14-X
5. 15X-10=6X-(X-2)+(-X+3)
6. X+3(X-1)=6-4(2X+3)
7. 6-3(X+1)= -4X+2(1-X)
ENSERIO AYUDENMEEEEEEEEEEE

Explicación paso a paso:
5X - 7 + 2X = 4X + 5
5X + 2X - 4X = 7 + 5
3X = 12
= 12 ÷ 3
= 4
5X - 2X - 4 = X + 7 - 5
5X -2X -X = 7 - 5 + 4
2X = 6
= 6 ÷ 2
= 3
X - ( 2X + 1 ) = 8 - ( 3X + 3 )
X - 2X - 1 = 8 - 3X - 3
-X - 1 = 5 - 3X
-X +3X = 5 + 1
2x = 6
= 6 ÷ 2
= 3
2 ( X + 1) - 5 = 14 - X
2X + 2 - 5 = 14 - X
2X - 3 = 14 - X
2X + X = 14 + 3
3X = 17
= 17 ÷ 3
=17/3
15X - 10 = 6X - ( X - 2 ) + ( -X + 3 )
15X -10 = 6X - X + 2 -X + 3
15X -10 = 4X + 2 + 3
15X -10 = 4X + 5
15X - 4X = 5 + 10
11X = 15
= 15 ÷ 11
= 15/11
X + 3 ( X - 1 ) = 6 - 4 ( 2X + 3 )
X + 3X - 3 = 6 - 8X - 12
4X - 3 = -6 - 8X
4X + 8X = -6 + 3
12X = -3
= -3 ÷ 12
= -1/4
6 - 3 ( X + 1 ) = - 4X + 2 ( 1 - X )
6 - 3X - 3 = 4X + 2 - 2X
3 - 3X = 2X + 2
- 3X - 2X = 2 - 3
-5X = - 1
= -1 ÷ -5
= 1/5
