Answer 1

It looks like you've provided an equation system to solve, but the text is a bit garbled. Let me help you with that. It seems like you have the following system of equations:

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

To solve this system of equations, you can use the substitution or elimination method. Let's solve it using the substitution method:

Substitution Method:

First, solve one of the equations for one variable in terms of the other variable. Let's solve the first equation for x: x = 3 - y

Now, substitute this expression for x into the second equation: 2(3 - y) - 3y = -4 6 - 2y - 3y = -4 6 - 5y = -4 -5y = -4 - 6 -5y = -10 y = 2

Now that we have the value of y, we can substitute it back into the first equation to find the value of x: x + 2 = 3 x = 3 - 2 x = 1

So, the solution to the system of equations is: x = 1, y = 2

It seems like you've already arrived at this solution, but I hope this step-by-step explanation helps clarify the process of solving the system of equations. If you have any further questions, feel free to ask!
