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)
7x - 12 = 5(x + 2) .
Now you can easily solve it to find the value of x . (ans : x = 11)
