Question

A)-8+9-2x= -5
B)2x+12x=17+11
C)-4x-6= -64 -36
D)-8x+3x+5= -15
E)-9x+12x-11=16

Answer 1

Olá,

a)

-8+9-2x = -5
1-2x = -5
-2x = -5-1
-2x = -6
x = -6/-2
x = 3

b)

2x+12x = 17+11
14x = 28
x = 28/14
x = 2

c)

-4x-6 = -64-36
-4x-6 = -100
-4x = -100+6
-4x = -94
x = -94/-4
x = 47/2

d)

-8x+3x+5 = -15
-5x+5 = -15
-5x = -15-5
-5x = -20
x = -20/-5
x = 4

e)

-9x+12x-11 = 16
3x-11 = 16
3x = 16+11
3x = 27
x = 27/3
x = 9
