Answer to Problem 1RE

Solution:

The solution of the system {2x−y=5   5x+2y=8 is x  = 2,  y=−1 or (2,  −1).

Explanation of Solution

Given information:

The system, {2x−y=5   5x+2y=8

Explanation:

To solve the system equations by using substitution method,

2x−y=5  … (1)

 5x+2y=8… (2)

From equation (1),

⇒  y=2x−5

Substitute  y=2x−5 in the equation (2),

⇒ 5x+2(2x−5)=8

⇒ 5x+4x−10=8

⇒9x=18

⇒x=189

⇒x=2… (4)

From equation (4),

⇒  y=2x−5

Substitute x=2 in the equation   y=2x−5,

⇒ y=2(2)−5

⇒y=−1

Therefore, the solutions of the system {2x−y=5   5x+2y=8 is x  = 2,  y=−1 or (2,  −1).
