28
x=28
Divide 28 by 4. X = 7
There's nothing to solve. If it equaled something, you could solve it. For example, if x^2 - 28 = 0, then x = the square root of 28, which simplifies to plus or minus 2 times the square root of 7.

2/7=x/28 56=7x 8=x
You want an equivalent fraction for 7/28 where the denominator is 100. that is 7/28 = x/100 This will solve to x = 25
To find what x multiplied by 7 equals 28, you can set up the equation 7x = 28. To solve for x, divide both sides by 7: x = 28 / 7. Simplifying, x = 4. Therefore, 4 multiplied by 7 equals 28.

30-2=28 so 2x=28 28 divided by 2=14, so x is 14
Take the square root of each side of the equation.x = ± i sqrt(28)
Set up your equation 28/x = 112/100 (that's 28 divided by x = 112 divided by 100). Then you can cross-multiply (giving you 2800 = 112x) and solve for x (which in this case is 25).
