7x-3y=21
Think of it this way. Block 3y or multiply 3(0)=0. Then you get:
7x=21
X=3
In vice versa, block 7x or multiply 7(0)=0 and look at:
3y=21
Y=7
So an ordered pair is (x,y)
Thus, you get (3,7)
To find the ordered pair for the equations (3x + 5y = 21) and (-9x + 4y = -6), we can solve this system of equations. By using substitution or elimination methods, we find that (x = 3) and (y = 2). Thus, the ordered pair is ((3, 2)).
The order of operations which equals 229 is (2000/10) + (50-21) =229.
If the order of the dice is irrelevant, then the answer is 21. If the order of the dice is relevant, the answer is 36.
28*21 equals 84

x = 2, y = 3

Rearrange the equations in the form of:- 6x-6y = 17-11 -4x+6y = 21 6x-6y = 6 -4x+6y = 21 Add both equatios together in order to eliminate y: 2x = 27 Divide both sides by 2: x = 13.5 Substitute the value of x into the equations to find the value of y: x = 13.5 and y = 12.5
This is not correct. If x=11, then 9+x=20. In order for 9+x=21 to be correct, x would have to be equal to 12.
21 equals dots on a dice
28*21 equals 84

(1, 21)(3, 7)
21 is not prime.
5q-29 equals 21 5q equals 50 q = 5
