To verify if Sehyr made an error in her work, let's solve the equation w/2−7=11 step by step:
w/2 - 7 = 11
First, we isolate the variable term by adding 7 to both sides:
w/2 = 11 + 7
w/2 = 18
Next, we can cancel out the division by 2 by multiplying both sides of the equation by 2:
2 * (w/2) = 2 * 18
w = 36
Therefore, according to the calculations, the solution to the equation is w = 36.
To confirm if the solution is correct or not, we substitute the value of w back into the original equation:
36/2 - 7 = 18 - 7
18 - 7 = 11
Since the equation holds true, we can conclude that Sehyr did not make an error in her work. The solution w = 36 is correct and does work.
Sehyr solved the equation w/2−7=11. She seems to have made an error in her work because the solution she found does not work.
