2x+5=8
-2x       -2x
5= 6x
divide by 6 on both sides
.8333=x  (it's a repeating decimal)   

12(.8333)= 9.9996 (depending on how the teacher like it rounded)

The required value of 12x is 10

Given the expression

2x + 5 = 8x

Subtract 8x from both sides

2x + 5 - 8x  = 8x - 8x

2x - 8x + 5 = 0

-6x + 5 = 0

Subtract 5 from both sides

-6x + 5 - 5 = 0 - 5

-6x = -5

x = -5/-6

x = 5/6

Next is to get the value of 12x

12 x = 12(5/6)

12x = 2 × 5

12x = 10

Hence the value of 12x is 10
