x+y=3

Answer 2

To solve the system of equations:

Equation 1: x - y = -4 Equation 2: x + 2y = 5

There are multiple methods to solve this system of equations. One common method is substitution. Here's how you can solve it step by step:

Step 1: Solve Equation 1 for x. x = -4 + y

Step 2: Substitute the value of x from Equation 1 into Equation 2. (-4 + y) + 2y = 5

Step 3: Simplify and solve for y. -4 + y + 2y = 5 3y - 4 = 5 3y = 5 + 4 3y = 9 y = 9/3 y = 3

Step 4: Substitute the value of y back into Equation 1 to find x. x - 3 = -4 x = -4 + 3 x = -1

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