Question

Elimination methid of ,2x+5y=10 ,5x+y=25

Answer 1

Answer:

x = 5, y = 0

Step-by-step explanation:

The two equations are

2x + 5y  = 10                        (1)

5x + y    = 25                       (2)

equation(1) × 5, 10x + 25y = 50                         eq(3)

equation(2) × 2, 10x + 2y  = 50                         eq(4)

eq(3) - eq(4)

17y = 0

y    = 0

from eq(1)

2x =    10

x  =      5
