Question

If 2x+5=8x then 12x=?

Answer 1

2x+5=8x

5=6x

x=5/6

12(5/6)

x=10

Answer 2

The value of 12x is 10

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
