10) - 35 - 4q = - 7

CON PROCEDIMIENTOS.. DOY 28 PTS.

Answer 1

 2x = - 16
   x = -8


 5a = - 75
   a = -75/5
  a = -15

x ÷ 3 = 16
x = 16/3


13n = - 26
x = -26/13
x = -2


-10b = - 20
b = -20/-10
b = 2


-48 = - 6x
-48/-6 = x
8 = x

4x = - 28
x = -28/4
x = -7

x ÷ 4 = 100
x = 100(4)
x = 400


- 24 + 7 = - 17c
-17 = -17x
-17/-17 = x
1 = x


- 35 - 4q = - 7
-35+7 = 4q
-28 = 4q
-28/4 = q
-7 = q
