Question

x - 5y = 10
2x + 5y = 5

Answer 1

Answer:

x=5

y=-1

Step-by-step explanation:

equation(1) x-5y=10

equation(2) 2x+5y=5

step1: using addition method add both equations together.

    x-5y=10

+

    2x+5y=5

→(1+2)x+(-5+5)y=(10+5)

3x=15

(divide 3 for both sides)

x=5

step2: sub 5 for x into one of the equations.

x-5y=10  (x=5)

5-5y=10

(subtract 5 for both sides)

-5y=5

(divide -5 for both sides)

y=-1
