Solve the following equation algebraically. Show your work.
13+w7=−18
To solve the equation algebraically, we need to isolate the variable w.
Starting with the given equation:
13 + w7 = -18
First, we will subtract 13 from both sides of the equation to isolate the term with w:
13 + w7 - 13 = -18 - 13
w7 = -31
Next, we will divide both sides of the equation by 7 to solve for w:
(w7) / 7 = (-31) / 7
w = -31 / 7
Therefore, the solution to the equation 13 + w7 = -18 is w = -31 / 7.
