Answer 2

a)26-10x-15=x

-10x-x = -26+15

-11x = -11

x = 11/11

x = 1

b)9-x+4x-3=5x

-x+4x-5x = -9+3

-2x = -6

x = 6/2

x = 3

c)4(3-2X)=-5(2X)-6

12-8x = -10x-6

-8x+10x = -12-6

2x = -18

x = -18/2

x = -9

d)4+1+14x=-x+5x+3

14x-x-5x = 3-4-1

8x = -2

x = -2/8

x = -1/4

e)8+2+2x+x-5=-5x-2+x

2x+x+5x-x = -2-8-2+5

7x = -7

x = -7/7

x = -1

f)23+x-18=x(-4)-15

23+x-18 = -4x-15

x+4x = -15-23+18

5x = 20

x = 20/5

x = 4

Boa noite ❤️
