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
