Ten times a number, x, is one-half the sum of the number and three.
Ten times a number x = 10x
sum of the number and three = x + 3
one-half the sum of the number and three = 1/2 (x + 3)
So, the equation will be:
10x = 1/2 (x + 3)
if we solve this, we can also find he value of x
20x = x + 3
20x - x = 3
19x = 3
x = 3/19
S0, the number is 3/19 and equation is 10x = 1/2 (x + 3).
