Question

1 by 4 of a number is added to 1 by 3 of that number the result is 15 greater than half of that number find the number

Answer 1

x\4+x\3=x\2+18
7x\12(LCM)=(x+36)\2
14x=12x+432
2x=432
x=216

Answer 2

Answer:

180

Step-by-step explanation:

STEP 1 : Define x

Let the number be x

STEP 2: Form equation

x/4 + x/3 = x/2 + 15

STEP 3: Solve x

7x/12 = x/2 + 15

7x/12 - x/2 = 15

1x/12 = 15

x = 180

STEP 4: Find the number

Number = x = 180
