Question

B) 2x+11=x-13

C) 18-4x=27-3x

D) -13+5x=x-10

E) 25-7x+10=-3x+12-x


Resolva essas equações

Answer 1

Resposta:

b) -24

c) - 9

d) 3/4

e) - 22/9

Explicação passo a passo:

B) 2x+11=x-13

2x-x=-13-11

x = -24

C) 18-4x=27-3x

-4x+3x=27-18

-x=9 .(-1)

x=-9

D) 5x-x=-10+13

4x = 3

x = 3/4

E) -7x+35 = 2x+12

-7x-2x = 13-35

-9x = -22

x = 22/9

Answer 2

B) 2x+11=x-13
2x - x = - 13 - 11
x = - 24
________________

C) 18-4x=27-3x
18 - 27 = 4x - 3x
- 9 = x
x = - 9
____________
D) -13+5x=x-10
5x - x = -10+13
4x = 3
X = 3/4

E) 25-7x+10=-3x+12-x
35 - 7x = - 4x + 12
35 - 12 = 7x - 4x
23 = 3x
3x = 23
x = 23/3
