Given the numerical expression:

(10x) + 3

Determine its equivalent value.

Solution:

In order to determine its equivalent value, we simply need to combine like terms. In our case we are given a term and a constant, which means that we cannot simplify or combine further due to the fact that it must be similar terms.

= (10x) + 3

= 10x + 3

However, we can solve for x, by transposing 3 on the other side of the equation, hence we must take note that in transposing a number, the sign changes.

10x = -3

Divide both sides by 10 in order to cancel out  10x, leaving behind x.

10x/10 = -3/10

x = -3/10 

Final answer:

= 10x + 3

x = -3/10
