Question

Ayudenmen por favor es para mañana!!!!!!
Ecuaciones:
1)_ -X+6=-7
2)_ 4-X:3=-1
3)_ 125+(-X)=75
4)_ 5-X:3=1

Answer 1

- x + 6 = - 7

- x = - 7 - 6

- x = - 13

x = 13
------------------

4 - x/3 = - 1

- x/3 = - 1 - 4

- x/3 = - 5

- x = - 5 * 3

- x = - 15

x = 15
---------------------

125 + (- x) = 75

125 - x = 75

- x = 75 - 125

- x = - 50

x = 50
---------------------------

5 - x/3 = 1

- x/3 = 1 - 5

- x/3 = - 4

- x = - 4 * 3

- x = - 12

x = 12

Answer 2

1) -x+6=-7 7+6=x 13= x 2)4-x :3=-1 5= 3x 5/3= x 3) 125 -x=75 50= x 4) 5-x :3= 1 6 : 3= x 2= x
