Question

11 Resuelve.
a) 4x - 2x = 2x + 10 - 2x
b) 2x - 15 = 3x + 4
C) -x + 5 = 2x - 10
d) 4x + 2 - X = 12x + 10 - 3x​

Answer 1

a) 4x-2x=2x+10-2x

2x=2x+10-2x

2x=10

x= 10/2

x=5

b) 2x-15=3x+4

2x-15-3x=4

-x-15=4

-x=4+15

-x=19

x=-19

c)-x+5=2x -10

-x+5=-20

-x=-20-5

-x=-25

x=25

d) 4x + 2 - X = 12x + 10 - 3x

3x + 2 = 9x + 10

3x - 9x = 10-2

-6x= 10-2

-6x= 8

x= - 4/3
