Answer:

The value of 12x is 10

Step-by-step explanation:

We need to find the value of 12x

The given expression is 2x + 5 = 8x

Subtract 2x from both the sides in above expression,

2x + 5 - 2x = 8x - 2x

              5 = 6x

Multiply both the sides by '2' in above expression

2(5) = 2(6x)

10 = 12x

Hence, the value of 12x is 10
