w + 2x + 3w - 2xw = 2x + 4w - 2xw, in simplest form
25y2 - 49w2 = (5y)2 - (7w)2 = (5y - 7w)(5y + 7w)
56w2 + 17w - 3 = 56w2 + 24w - 7w - 3 = 8w(7w + 3) - 1(7w + 3) = (7w + 3)(8w - 1)
Let's start with making the variables coefficient a positive number. This obtained by simply multiply the negative fraction by -1/1, which results in the same fraction just positive. However, what you do to one side you must always do to the other. -2/7w = 8 -1/1 x -2/7w = 8 x -1/1 = 2/7w = -8 Now we see that our variable is still attached to the coefficient by means of multiplication. We must perform the inverse operation to detach the variable. In our case, division will suffice. 2/7w ÷ 2/7 = -8 ÷ 2/7 1/w = -8 ÷ 2/7 1/w = -28 w = -1/28. Is it (-2 over 7)w or -2 over (7w)?

w + 2x + 3w - 2xw = 2x + 4w - 2xw, in simplest form
-63=7w
To rearrange the equation v/(7x) = w/y to solve for x, you can start by multiplying both sides by 7x to eliminate the denominator on the left side. This gives you v = 7wx/y. Next, isolate x by dividing both sides by 7w/y, resulting in x = v/(7w/y), which simplifies to x = vy/(7w).

Factors of 14w are: 1, 2, 7, 14, w, 2w, 7w, and 14w .
7w - 4w - 6w = (7 - 4 - 6)w = -3w
7w=122 122/7= 17.43 w=17.43
3w + 4e + 7w - e3 = 10w - e
