Larry thought of a number. He added 1, multiplied the sum by 2, divided the product by 3, and then subtracted 4. He got 6. What
antoniya [11.8K]

Answer: Larry thought of the number 14

Step-by-step explanation:

Let the number be represented by x

Such that when added with 1 becomes x+1

Multiplied by 2 becomes 2(x+1)

divided  by 3 gives 2(x+1)/3

Upon subtraction with 4, we have

2(x+1)/3 -4=6 as the equation

Solving

2(x+1)/3 -4=6

2(x+1)/3=6+4

2(x+1)/3=10

2(x+1)=3x10

2(x+1)=30

2x+2=30

2x=30-2

2x=28

x=28/2

x=14
