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)

How do you solve 6x-6y plus 11 equals 17 6y equals 4x plus 21 in an order pair?
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
