Question

x+y=6
2x-y=3


2x+3y=2
5x-3y=5

6a+3b=b
9a+6b=1​

Answer 1

Explicación paso a paso:

X+Y=6

2X-Y=3

3X=9

X=3

X+Y=6

3+Y=6

Y=3

2X+3Y=2

5X-3Y=5

7X=7

X=1

2X+3Y=2

2(1)+3Y=2

2+3Y=2

3Y=0

Y=0

6a+3b=b (-9)

9a+6b=1 (6)

-54a-27b=-9b

54a+36b=6

9b=-9b+6

9b+9b=6

18b=6

b=1/3

6a+3b=b

6a+3(1/3)=1/3

6a+1=1/3

6a=1/3 - 1

6a= - 2/3

a= - 1/9
