Answer:

a = 5

b = 1

Step-by-step explanation:

-a + 5b = 0 ------- (i)

2a - 4b = 6 ------- (ii)

(-a + 5b = 0) × 2

-2a + 10b = 0 ------- (iii)

Add (ii) and (iii) ,

2a - 4b + (-2a + 10b) = 6 + 0

2a - 4b -2a + 10b = 6 + 0

6b = 6

b = 6/6

b = 1

-2a + 10b = 0

-2a + 10(1) = 0

-2a = -10

a = -10/-2

a = 5
