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

a = 11 : 4

b = 38

c = 1 for every 6

it will cost dollar $540

the living room is 3 which means if we divide 325/3 then we get $108

therefore if 1part of the living room cost $108 and 3 costed $325

then total 5part of the room will cost 5*108 which gives $540
