Question

gauss elimination x+2y=2,2x+3y=5

Answer 1

Answer:

x = 4

y = -1

Step-by-step explanation:

(x + 2y = 2) × 2 ----- (i)

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

2x + 3y = 5 ----- (iii)

Using Elimination method,

Subtract (iii) - (ii)

2x + 3y - (2x + 4y) = 5 - 4

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

-y = 1

y = -1

2x + 3y = 5

2x + 3(-1) = 5

2x - 3 = 5

2x = 5 + 3

2x = 8

x = $\frac{8}{2}$

x = 4
