Question

The sum of twice a number and 4 is equal to the sum of the number and 3.

Answer 1

Answer:

number = - 1

Step-by-step explanation:

let the number be n then twice the number is 2n , so

2n + 4 = n + 3 ( subtract n from both sides )

n + 4 = 3 ( subtract 4 from both sides )

n = - 1

The number is - 1
