Question

use the elimination method to solve thefollowing system of equation 5x+y=19 x-2y = 6

Answer 1

Answer:

x = 4 and y = -1

Step-by-step explanation:

5x + y = 19 ... (1)

x - 2y = 6 ... (2)

Using Elimination method,

2 × Equation (1) + Equation (2)

10x + 2y = 38

+ x - 2y = 6

11x = 44 Divide both sides by 11

x = 44/11

x = 4

Also, Equation (1) - 5 × Equation(2)

5x + y = 19

-5x - 10y = 30

11y = - 11 Divide both sides by 11

y = -11/11

y = -1

Hence,

x = 4 and y = -1
