Question

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

Answer 1

1. 4
2. 3
3. 3
4. 17/3
5. 15/11
6. -1/4
7. 1/5

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
