4 x 3 = 12 so 12 + 50x = 250 so 50x=250-12 50x = 238 x = 238/50 x = 4.76
X=5.2
4x2+50x = 0 4x(x+12.5) = 0 x = 0 or x = -12.5
10 + x = 50x = 40
18t + 4x -47t + 50x = -29t + 54x

Cubic and higher polynomials are difficult to solve; you can use Excel Solver to do it for you, or a Web site like Wolframalpha. On this site, type the input as: solve 4x^3 + 50x = 250. Here is the result:http://www.wolframalpha.com/input/?i=solve+4x^3+%2B+50x+=+250As you can see, the equation has one real solution, and two complex solutions.If you want to solve it yourself:Put the 250 to the left:4x3 + 50x - 250 = 0Divide by 2:2x3 + 25x - 125 = 0Any rational root (solution) of this has a numerator that is a factor of 125 (options are 1, -1, 5, -5, 25, -25, 125, -125), and a denominator that is a factor of 2 (1, -1, 2, -2). This gives you a total of 14 combinations.In this case, that won't work (since the solutions are not rational). The easiest method is to try different numbers for "x", until you get close to a solution.
18t + 4x -47t + 50x = -29t + 54x

50x and 60y
10x plus 40 is 50x.10+40=50 and then you just add the x so:10x+40=50x
Multiply These Equals What you mix 50 .10+x 5+50x Plus what you have 90 .10 9 Equals what you need 40 x 40x 5+50x+9=40x 14+50x=40x 10x=14 x=1.4 140%
If you mean:0 = 800 - 10x + 25 * 20 = 800-10x+25*210x = 800+50x = 8,50 = 800 - 10x + 25 * x * 20 = 800 - 10x + 50x-800 = 40x-50 = x
50x squared equals 20x-2 equals zero is not possible, for 20x-2 = 0 --> x = 1/10 While 50x2 = 0 means that x should be zero. So either 50x2 =/ 20x-2 or 20x-2 =/ 0
