So we have:
xk = v + w solve for x
divide both sides by k to isolate the variable x:
x = (v+w)/k
^^This is your answer!
Hope I helped!
The answer is 6,889. Squared just means the number times itself. In this case, it's 83 x 83. :)
1/3 x - 1/2 = 18 1/2
1/3 x = 19 (add 1/2 on the right side to 18 1/2)
x = 57 (multiply the reciprocal of 1/3 and that will be 3/1 or 3 to 19 to get x by itself)
So, the answer is x = 57 (d. 57)
