Given the equation:
-79 = 7w + 3(4w – 1)
Solve for w.
Solution:
In order to solve for w, we start first by distributing 3 to each value inside the parenthesis.
-79 = 7w + 3(4w - 1)
-79 = 7w + 12w - 3
Combine similar terms.
-79 = 19w - 3
Transpose -3 to the other side of the equation, hence it must be taken to note that in transposing a number, the sign changes.
19w = -79 + 3
19w = -76
19w/19 = -76/19
w = -4
Final answer:
w = -4
