Math Problem Statement

Solve the system using the elimination method. Write the solution as an ordered pair. 3x + 2y = 3 2x + 3y = 2

Solution

The image presents a system of linear equations that you need to solve using the elimination method:

3x+2y=33x + 2y = 3 2x+3y=22x + 3y = 2

To use the elimination method, we aim to eliminate one of the variables by multiplying both equations by suitable numbers so that the coefficients of one of the variables match. Let's go through the solution step-by-step.

Step 1: Eliminate one variable

We can eliminate xx by making the coefficients of xx in both equations the same. To do this, we multiply the first equation by 2 and the second equation by 3.

  • Multiply the first equation by 2: 2(3x+2y)=2(3)2(3x + 2y) = 2(3) 6x+4y=66x + 4y = 6

  • Multiply the second equation by 3: 3(2x+3y)=3(2)3(2x + 3y) = 3(2) 6x+9y=66x + 9y = 6

Now, we have the system: 6x+4y=66x + 4y = 6 6x+9y=66x + 9y = 6

Step 2: Subtract the equations

Next, subtract the first equation from the second to eliminate xx: (6x+9y)(6x+4y)=66(6x + 9y) - (6x + 4y) = 6 - 6 5y=05y = 0 y=0y = 0

Step 3: Substitute y=0y = 0 into one of the original equations

Now that we know y=0y = 0, substitute this value into one of the original equations to solve for xx. Let's use the first equation:

3x+2(0)=33x + 2(0) = 3 3x=33x = 3 x=1x = 1

Final Solution:

The solution is x=1x = 1 and y=0y = 0, or as an ordered pair:

(1,0)(1, 0)
