Can someone check if I'm correct please.
13 + w/7 = -18
(7)13+(7)w/7= (7)-18
91 + w = -126
91-91 + w = (91)-126
w = 217
Thanks!
13 + w/7 = -18
w/7 = -31
w = -217
You forgot the sign.
Thanks!
You're welcome.
To check if your answer is correct, you can substitute the value of w back into the original equation and see if it holds true.
Let's do that:
13 + w/7 = -18
Substituting w = 217:
13 + (217)/7 = -18
Calculating:
13 + 31 = -18
This simplifies to:
44 = -18
Since 44 and -18 are not equal to each other, it means that your original answer of w = 217 is incorrect. Therefore, you will need to recalculate the solution to the equation.
