Answer:

solution: (9, 3) ,   x = 9, y = 3

Step-by-step explanation:

Negative 4 x + 6 y = negative 18 and y = negative 2 x + 21

convert to algebra.

- 4x + 6y = -18 ;

y = -2x + 21;

let us solve this with elimination

change -4x + 6y = -18  to  -2x + 3y = -9

get:  -2x  + 3y = -9

and  2x + y = 21

add.

-2x + 2x + 3y + y = -9 + 21

4y = 12

y = 3

2x + (3 ) = 21

2x = 18

x = 9

(9, 3)

Is 0.26 is closer to 0, 1/2 or, 1
professor190 [17]
Here, we know 1/2 = 0.50
So, the difference between 0.50 & 0.26 is 0.24
And difference between 0 and 0.26 is 0.26
1 is very apart from 0.26 as compared to other two

So, It is closer to 1/2

Hope this helps!

Two equations are given below:
goldenfox [79]
Since the second equation gives a value for a, we can substitute it into the other equation to find a value for B.

Let's substitute b-2 into the first equation wherever there is an a.

a - 3b = 4
(b-2) - 3b = 4
b - 2 - 3b = 4
-2 - 2b = 4
-2b = 6
b = -3

Now let's find a by substituting -3 into either of the equations to find the value of a.

a = b - 2
a = -3 - 2
a = -5

So your solution set  is (-5, -3)
