Given the statement:
Six times the sum of a number and twelve is forty
Explanation:
Times means that we will be using the operation of multiplication and sum means that we will be using the operation of addition, hence we can write the numerical equation for the given statement as,
6(N+12) = 40
We can find the value of the number by distributing 6 to each value inside the parenthesis.
6N + 72 = 40
Transpose 72 on the other side of the equation, note that when transposing a number, the sign changes.
6N = 40 -72
6N = -32
Divide both sides by 6 in order to get the value of N.
N = -32/6 or -16/3
Final answer:
6(N+12) = 40
