"one-half the sum of the number and three" ----->represent
therefore
The complete expression represent
Given a number "x"
ten times this number is : 10x
one-half the sum of the number and three= 1/2(x+3)
Therefore:
The equation will be:
10x=1/2(x+3)
20x=x+3
20x-x=3
19x=3
x=3/19
Answer: the equation is : 10x=1/2(x+3) and the number is 3/19.
