-2(5+4x) = 14
Distribute the -2:
-2*5+-2*4x = 14
-10-8x = 14
Add 10 to both sides:
-10-8x+10 = 14+10
-8x = 24
Divide both sides by -8 =
(-8x)/(-8) = 24/-8
x = -3

Hi, this is a mathematical eqaution, you have to find the value of x in this.
this can be solved as follows:
-2*5 -(+)2*4x = 14
this implies:
-10 - 8x = 14
-10 - 14 = 8x
-24 = 8x
this implies x = -24/8
i.e. x = -3

distribute
-2*5 + -2*4x = 14
-10 -8x = 14
carry 10 over to other side (add it to both)
-8x = 24
divitde
x = -3

-10 - 8x = 14
8x = 14 + 10
8x = 24
x = 24 / -8
x = -3

-2(5+4x)=14
expand: -10-8x=14
move like terms to one side: -8x=24
divide by -8: x=-3\
therefore x=-3

-10 - 8x = 14
-8x = 14 + 10
-8x = 24
(divide both sides by negative eight to get x.)
x= -3

-10+-8x=14
-14 =-14+8x
-24=8x
-24/8=x
-3=x
