-2x + 3y =-9<br> X+y = 2
geniusboy [140]

Answer:

The values of x and y to the given equation are x=3 and y=-1

The solution to the given equation is (3,-1)

Step-by-step explanation:

Given equations are -2x+3y=-9\hfill (1)

x+y=2\hfill (2)

To solve given equations by using elimination method :

Mutliply the equation (2) into 2 we get

2x+2y=4\hfill (3)

Now adding the equations (1) and (3)

-2x+3y=-9

2x+2y=4

_______________

5y=-5

y-\frac{5}{5}

Therefore y=-1

Now substitute the value of y=-1 in the equation (1) we get

-2x+3(-1)=-9

-2x-3=-9

-2x=-9+3

=-\frac{-6}{-2}

Therefore x=3

The values of x and y to the given equation are x=3 and y=-1

The solution to the given equation is (3,-1)

Hene odds= favourable:unfavourable =3/7

Answer is 3/7

b) Given that odds against choosing a blue block are 13/4

This means there are 4 blue blocks and 13 other colour blocks.

Total blocks= 13+4 =17

No of blue blocks = 4

Probability of selecting blue block=4/17
