Answer:
Certainly, here's the solution to the system of equations using the Gaussian elimination method step by step:
Given equations:
1. 3x - 2y = 7
2. 2x + 4y = 10
Step 1: Multiply equation (1) by 2 to make the coefficients of y cancel when added to equation (2):
2(3x - 2y) = 2(7)
6x - 4y = 14
Step 2: Now, you have the following system of equations:
1. 6x - 4y = 14
Step 3: Add equation (2) to equation (1) to eliminate y:
(6x - 4y) + (2x + 4y) = 14 + 10
8x = 24
Step 4: Divide both sides by 8 to solve for x:
x = 24 / 8
x = 3
Step 5: Substitute the value of x into equation (1) to solve for y:
3x - 2y = 7
3(3) - 2y = 7
9 - 2y = 7
Step 6: Subtract 9 from both sides:
-2y = 7 - 9
-2y = -2
Step 7: Divide both sides by -2 to solve for y:
y = -2 / -2
y = 1
So, the solution to the system of equations is x = 3 and y = 1.
