Question

1) resolva as equações: a)14(x-2)=10(x+3)= b) 4(x-1)+2(x-5)=0 c)3(2x-1)-2(x-5)=x-5

Answer 1

a) 14(x-2)=10(x+3)

14x-28=10x+30

14x-10x=30+28

4x=58

x=58/4

x=14,5

b) 4(x-1)+2(x-5)=0

4x-4+2x-10=0

4x+2x = 0+10+4

6x=14

x=14/6

x=2,333...

c) 3(2x-1)-2(x-5)=x-5

6x-6-2x-5=x-5

6x-2x-x=5+5+6

3x=16

x=16/3

x=5,333...

espero ter ajudado

Answer 2

a) 14(x-2)=10(x+3)
14x-28=10x+30
14x-10x=30+28
4x=58
x=58/4
x=29/2

b)4(x-1)+2(x-5)=0
4x-4+2x-10=0
4x+2x=10+4
6x=14
x=14/6
x=7/3

c) 3(2x-1)-2(x-5)=x-5
6x-3-2x-10=x-5
6x-2x-x= -5+3+10
3x=8
x=8/3
