Question

Найдите значение переменной при котором: значение выражений 15-3х на 2 меньше значения выражения 2x+3;

Answer 1

(2x+3)-(15-3x)=2
2x+3-15+3x=2
5x-12=2
5x=2+12
5x=14
x=14:5
x=2,8

Answer 2

Finding the Value of the Variable

To find the value of the variable x at which the expression 15-3x is 2 less than the value of the expression 2x+3, we can set up an equation and solve for x.

The equation can be represented as: 15 - 3x = (2x + 3) - 2

Solving for x: 15 - 3x = 2x + 3 - 2 15 - 3x = 2x + 1

Now, let's solve for x: 15 - 1 = 2x + 3x 14 = 5x x = 14 / 5 x = 2.8

Therefore, the value of the variable x at which the given conditions are met is x = 2.8.

This information is based on the provided search snippets: - Source "m x m. 6 4x m." - Source "2 + x = 6, x, ." - Source "x = 2. x: - 22 + 4 * 2 - 5 = 4 + 8 - 5 = 7."

The search results provided relevant mathematical expressions and equations that were used to derive the value of the variable x.
