Question

verificar ecuaciones (hechas) ayuda porfavor!

A- 10x +15 +4 = 37+ 4x
10x + 19 = 37+ 4x
10x - 4x = 37 - 19
6x = 18
x = 18/6
x = 3

B- 9x-6=3x+6
9x-3x=6+6
6x=12
x=2

C- 9x+45-5x=16+5.6+3x
4x+45=16+30+3x
4x+45=46+3x
4x-3x=46-45
x=1

D-36+59=(20x+10):2
36+59 = 20x: 2 + 10 :2
95 = 10x + 5
95 - 5 = 10x
90 = 10x
9 = x

E- (x+6)·9+19 = 181
9·x+9·6+19 = 181
9x+54+19 = 181
9x = 181-54-19
9x = 108
x = 108÷9
x = 12




F- 6.(3x+5)=3.(20+x)
18x+30=60+3x
18x-3x= 60-30
15x= 30
x=2

G- 17 x-5= 10x+5-3
17x - 5 = 5. (2x + 1) - 3
17x - 5 = 10x + 5 - 3
17x - 10x = 5 - 3 + 5
7x = 7
x = 7 ÷ 7
x = 1

H- 3.( x - 6) = (2x + 1).5 - 8.9
3x - 18 = 10x + 5 -72
- 18 + 72-5 =10x - 3x
49 = 7x
49/7 = x
7 = x

Answer 1

Respuesta:

a) 10×3+15+4=37+4×3

30+15+4=37+12

49=49

b) 9×2-6=3×2+6

18-6 = 6+6

12=12

c) 9×1+45-5×1=16+5×6+3×1

mal f

d) 36+59=(20×9+10)÷2

mal

e) (12+6)×9+19= 181

18×9 +19=181

162+19=181

181=181

f) 6×(3×2+5) = 3 (20+×2

mal

g) 17×1-5=10×1+5-3

17-5 = 10+5-3

12=12

h) 3×(7-6) =(2×7+1) ×5-8×9

3×1=(14+1)×5-72

3= 15×5-72

3=75-72

3=3
