Question

Срочно При каком значении переменной x удвоенная сумма x и 3 равна - 14?

Answer 1

$2(x+3)=14 \\ x+3=7 \\ x=4$

Answer 2

Solving the Equation

To solve the equation where the doubled sum of a variable x and 3 equals -14, we can follow these steps:

1. Formulate the Equation: We start by formulating the equation based on the given information. 2. Solve for x: We then solve for the variable x using basic algebraic operations.

Formulating the Equation

The equation can be formulated as follows: 2(x + 3) = -14

Solving for x

To solve for x, we can follow these steps: 1. Expand the expression 2(x + 3). 2. Set the expanded expression equal to -14. 3. Solve for x.

Expanding the expression 2(x + 3): 2x + 6 = -14

Setting the expanded expression equal to -14: 2x + 6 = -14

Subtracting 6 from both sides: 2x = -20

Dividing both sides by 2: x = -10

So, the value of the variable x that satisfies the given equation is x = -10. This means that when x is -10, the doubled sum of x and 3 equals -14.
