Question

2х-5у=6 4х+5у рушите систему уравнения методом сложения

Answer 1

2x - 5y = 6

4x + 5y =24 ⇔

6x=30

2x-5y=6 ⇔

x=5

10- 5y= 6 ⇔

-5y= -4

x=5 ⇔

x=5

y=4 / 5

Ответ : (5 ;4/5)

Answer 2

To solve the system of equations using the method of addition, we'll add the two equations together. This will eliminate the variable 'у', allowing us to solve for 'х'.

Given equations:

1. 2х - 5у = 6
2. 4х + 5у = ?

Adding both equations together: (2х - 5у) + (4х + 5у) = 6 + ?

Simplifying the equation: 2х + 4х - 5у + 5у = 6 + ?

Combining like terms: 6х + 0 = 6 + ?

Simplifying further: 6х = 6 + ?

Now, we need the equation for 4х + 5у to determine the value of '?'. However, you didn't provide the equation for 4х + 5у. Please provide the missing equation so that we can continue solving the system of equations using the method of addition.
