Question

2х+3у=5 3у=5-2х 3у=3х у=

Answer 1

2х+3у=5

3у=5-2х

у=(5-2х)/3

придаете значение х, получаете значение у

например. х=1

у=(5-2*1)/3=1

и решение (1;1)

х=-1, у=7/3 и т.д. бесконечное множество ответов

Answer 2

To find the value of y in the given system of equations:

2x + 3y = 5 ---(1) 3y = 5 - 2x ---(2)

We can solve this system by substitution or elimination. Let's use substitution:

First, let's solve equation (2) for y: 3y = 5 - 2x Divide both sides by 3: y = (5 - 2x)/3

Now, substitute this value of y into equation (1): 2x + 3((5 - 2x)/3) = 5

Multiply through by 3 to clear the fraction: 2x + 5 - 2x = 15

Simplify: 5 = 15

This equation is not possible, as 5 cannot be equal to 15. Therefore, the system of equations is inconsistent, and there is no solution for x and y that satisfies both equations simultaneously.
