Question

Determine O valor De X ;
A)3x+2=13-8x
B)2(x+)-3(x-5)=9x
C)4(2x+13)+6(3x-1)=5(2x-3)+8
​

Answer 1

Resposta:

a)3x+2=13-8x

Explicação passo-a-passo:

a)3x+2=13-8x

3x+8x=13-2

11x=11

x=11/11

x=1

b)2(x +)-3(x-5)=9x

2x-3x+15=9x

2x-3x-9x=15

-10X=15 x(-1)

10x=-15

x=15/10

x= -1,5

c)4(2x+13)+6(3x-1)=5(2x-3)+8

8x+52+18x-6=10x-15+8

8x+18x-10x=-15+8+6-52

16x=-53

x=-53/16

x=-3,125

Answer 2

Resposta:

a) 3x+8x=13-2  

11x=11  

x=1

b) 2x-3x+15=9x  

-x-9x=-15

-10x=-15

x=-15/=-10

x=-3/-2

c) 8x+52+18x-6=10x-15+8

8x+18x-10x=-15+8-52+6

36x=-7-52+6

36x=-45+6

X=-39/36

x=13/-12
