When 2x2/y = w + 2/4 is solved for w, one equation is w= 8x2/y - 2. Which of the following is an equivalent equation to find w?
w = 8x2 + 2y/y, w = 8x2 - 2y/y, w = 8x2 - 3y, w = 8x2 - y
Solution:
Given: 2x2/y = (w + 2)/4
4(2x2) = y(w + 2)
By further calculation
8x2 = wy + 2y
Now isolate w
wy = 8x2 - 2y
Now divide by y on both sides
w = (8x2 - 2y)/y
Therefore, the equivalent equation is w = (8x2 - 2y)/y.
When 2x2/y = w + 2/4 is solved for w, one equation is w= 8x2/y - 2. Which of the following is an equivalent equation to find w?
Summary:
When 2x2/y = w + 2/4 is solved for w, one equation is w = 8x2/y - 2. The equivalent equation to find w is w = (8x2 - 2y)/y.
