Question

100/ (5 х+ 3х)=2 решите уровнение плиз!!!!

Answer 1

100/(5x-3x)=2
100/2x=2
2x*2=100
4x=100
x=100:4
x=25

Answer 2

Solving the Equation

To solve the equation 100 / (5 + x + 3x) = 2, we can follow these steps:

1. Simplify the expression inside the parentheses: 5 + x + 3x becomes 5 + 4x. 2. Rewrite the equation: 100 / (5 + 4x) = 2.

To isolate the variable x, we can multiply both sides of the equation by (5 + 4x):

100 / (5 + 4x) * (5 + 4x) = 2 * (5 + 4x).

Simplifying further:

100 = 2 * (5 + 4x).

Now, distribute the 2 on the right side of the equation:

100 = 10 + 8x.

Subtract 10 from both sides:

100 - 10 = 10 + 8x - 10.

Simplifying:

90 = 8x.

Finally, divide both sides by 8 to solve for x:

90 / 8 = 8x / 8.

Simplifying:

11.25 = x.

Therefore, the solution to the equation 100 / (5 + x + 3x) = 2 is x = 11.25.

Please note that this solution is based on the given equation and the mathematical operations used to solve it.
