Question

2x-3y=3 X-y=2 пжжооорр

Answer 1

Вот решила на листе бумаги. Х = 3; у = 1.

Answer 2

To solve the system of equations:

2x - 3y = 3
x - y = 2

There are multiple methods to solve this system, such as substitution, elimination, or matrix methods. I will demonstrate how to solve it using the elimination method.

Step 1: Multiply the second equation by 2 to eliminate the x-term.

2(x - y) = 2(2) 2x - 2y = 4

The modified system of equations becomes:

2x - 3y = 3
2x - 2y = 4

Step 2: Subtract the second equation from the first equation to eliminate the x-term.

(2x - 3y) - (2x - 2y) = 3 - 4 2x - 3y - 2x + 2y = -1 -3y + 2y = -1 -y = -1 y = 1

Step 3: Substitute the value of y into one of the original equations to solve for x. Let's use the second equation.

x - y = 2 x - 1 = 2 x = 2 + 1 x = 3

So, the solution to the system of equations is x = 3 and y = 1.
