Question

2a + 3b = 2 14a - 9b = -1​

Answer 1

Respuesta:

Explicación paso a paso:

2a + 3b = 2.........(1)

14a - 9b = -1​..........(2)

Multiplicando a (1) *3

6a+9b=6..(1)

14a-9b=-1..(2)

Sumando (1)+(2)

20a=5

a=5/20

a=1/4

Remplazando a=1/4 en (1)

2a + 3b = 2.........(1)

2(1/4)+3b=2

1/2+3b=2

3b=2-1/2

3b=3/2

b=(3/2)/3

b=3/6

b=1/2
