Question

(x-50)*6+70=490 5450:(204-5*x)=50

Answer 1

1) 6x = 720
X = 720/6 = 120
2)-250x + 4750/5x - 204 = 0
-250x = -4750
X = -4750/-250 = 19

Answer 2

Let's solve the equations step by step.

Equation 1: (x - 50) * 6 + 70 = 490

First, simplify the equation: 6(x - 50) + 70 = 490 6x - 300 + 70 = 490 6x - 230 = 490

Now, isolate the variable x: 6x = 490 + 230 6x = 720

Divide both sides by 6: x = 720 / 6 x = 120

So, the solution to equation 1 is x = 120.

Equation 2: 5450 / (204 - 5x) = 50

To solve this equation, let's first simplify it: 5450 = 50(204 - 5x)

Distribute 50: 5450 = 10200 - 250x

Now, isolate the variable x: 250x = 10200 - 5450 250x = 4750

Divide both sides by 250: x = 4750 / 250 x = 19

Therefore, the solution to equation 2 is x = 19.

So, the solutions to the given equations are x = 120 and x = 19.
