Question

Va rog eu mult am nevoie​

Answer 1

a)14=6(x+5)

14=6x+30

-6x=30-14

-6x=16

x=-8/3

b)2(4x+5)=6

4x+5=3

4x=3-5

4x=-2

x=-1/2

c)3(x+2)=12

x+2=4

x=4-2

x=2

d)3(1+5x)=8

3+15x=8

15x=8-3

15x=5

x=1/3

e)2(5-7x)=3

10-14x=3

-14x=3-10

-14x=-7

x=-1/2

f)5(2-3x)=7

10-15x=7

-15x=7-10

-15x=-3

x=1/5
