Question

Решите систему уравнения способом подстановки 4x+3y=5 x-y=7 x-y=3 5x-3y=1

Answer 1

Там же две системы, да?  Если да, то вот!Удачи!

Answer 2

Let's solve the system of equations step by step using the method of substitution. The given system of equations is:

1. $4x + 3y = 5$
2. $x - y = 7$
3. $x - y = 3$
4. $5x - 3y = 1$

Step 1: Solve equations 2 and 3 to get the value of $x$ and $y$ from one of the equations.

From equations 2 and 3, we have: $x - y = 7$ (Equation 2) $x - y = 3$ (Equation 3)

We can see that both equations have the same expression $x - y$, but they have different constants. Since they can't be true simultaneously, this system of equations doesn't have a solution. There might be a mistake in the formulation of the problem or the system of equations.

It's possible that you provided incorrect equations or made a typo. Please double-check the equations, and if you find any errors, feel free to provide the correct system of equations so that I can assist you further in solving it.
