Question

Если решение системы то сумма равна 1)1, 2); 3)3 4); 5) Помогите пожалуйста

Answer 1

0,2^(5x-y)=25⇒5^(y-5x)=5²⇒y-5x=2
{11^(2x-y)=1/121⇒11^(2x-y)=10^-2⇒2x-y=-2
прибавим
-3x=0
x=0
y=2
x0+y0=0+2=2

Answer 2

Solving the System of Equations

To solve the system of equations where the sum is equal to 1, we can use the given values: 1) (1, 2); 2) (3, 4); 3) (5, x).

The sum of the x-values is 1, and the sum of the y-values is also 1. Let's calculate the value of x.

The sum of x-values is 1, so: 1 + 3 + 5 = 9

The sum of y-values is 1, so: 2 + 4 + x = 6 + x

To find the value of x, we can set up the equation: 9 + (6 + x) = 1

Solving for x: 15 + x = 1 x = 1 - 15 x = -14

Therefore, the value of x in the system of equations is -14.
