Question

Rodney is given two linear equations: x – y = 11 and 2x + y = 19. What is the value of x in the solution to the system of equations?

Answer 1

Answer:

x = 10

Step-by-step explanation:

Given the 2 equations

x - y = 11 → (1)

2x + y = 19 → (2)

Adding (1) and (2) term by term will eliminate the y- term

(2x + x) + (y - y) = (19 + 11)

3x = 30 ( divide both sides by 3 )

x = 10

Answer 2

Answer:

x = 10
