G) 12x+16+2x=10x+56
H) 5.(2x+4)=3.(x+8)
ME AJUDEM POR FAVOR!!!

Answer 1

a) 2x +3x = 37 - 12

5x = 25

x= 25/5

x= 5

b) 4x + 60 = 2x -50

4x -2x = -50 -60

2x = - 110

x= -110/2

x= - 55

c) x +6x = 26-12

7x = 14

x= 14/7

x= 2

d) 8x + x = 1+80

9x = 81

x= 81/9

x= 9

e) 5x - 60 = 2x +8

5x -2x = 8+60

3x = 68

x= 68/3

f) 32x -30x = -40 +50

2x = 10

x= 10/2

x= 5

g) 14x +16 = 10x +56

14x - 10x = 56-16

4x = 40

x= 40/4

x= 10

h) 10x +20 = 3x +24

10x -3x = 24-20

7x = 4

x= 4/7
