if 12 subtracted from seven times a number is equal to five times the sum of the number and 2, find the number

Let the number be x , then the equation will be
7x - 12 = 5(x + 2) .

Now you can easily solve it to find the value of x . (ans :  x = 11)

  • 1

12-7x=5+(y+2)

and their is no answer of his equation because there are two variables(x and y)and linear equation says that there should be one variable

  • -2
