What is X?
2.4x=1.2x+15

x = 12.5

Step-by-step explanation:

2.4x=1.2x+15

Subtract 1.2x from each side

2.4x -1.2x=1.2x-1.2x+15

1.2x  =15

Divide by 1.2 on each side

1.2x/ 1.2 = 15/1.2

x = 12.5

12.5

Step-by-step explanation:

Let's solve this question using the step by step procedure

So let's solve

2.4x=1.2x+15

Let's collect like terms

2.4x-1.2x=15

1.2x=15

Let's make x the subject of formula by dividing both sides by 1.2

x=12.5

So the final answer is 12.5
