This is a relatively simple problem, when spread out in front of you. Let's start with:
Y=6X-5
Y=-X+9 or Y=9-X
Since we know that both expressions are equal to Y, they are therefore logically equal to each other as well. When we set them equal to each other, we get:
6X-5=9-X
Next, we get all of the X terms on one side:
7X-5=9
Finally, get all of the constants on the other side.
7X= 14
Now simply solve for X by dividing both sides by the coefficient of X (in this case 7)
X=2
Now that we know what X is equal to, we return to one of our Y= equations. Either one will do, if we did it right they should both equal the same thing. I'll do both here, as a check that we didn't make any arithmetic errors.
Y=6X-5 Y=9-X
Y=6(2)-5 Y=9-(2)
Y=12-5 Y= 7
Y=7
Since both Y's match, we know that we did it properly! In this system of equations, Y is equal to 7 and X is equal to 2

What is v plus 16 for v equals 9?
v + 16 when v = 9 Substitute 9 in where you see v. 9 + 16 = 25
N plus 3 - 9 if n equals 15?
If you know that n = 15, substitute 15 for n and solve: n + 3 - 9 15 + 3 - 9 9
What is 12 plus 9 equals?
12 plus 9 equals 21.
If x equals 9 and y equals 6 what is 10x plus 7y?
Substitute the values of x and y in 10x + 7y, thus: 10x + 7y = 10*9 + 7*6 = 90 + 42 = 132
Solve this equation -9h - 6 plus 12h plus 40 equals 22?
The solution to this equation is that h is equal to -4. You can substitute this value for h into the equation to get -4 x -9 - 6 plus 12 x -4 plus 40 equals 22, or 36 - 6 plus - 48 plus 40 equals 22.
What is v plus 16 for v equals 9?
v + 16 when v = 9 Substitute 9 in where you see v. 9 + 16 = 25
How do you group numbers 9 plus 8x7-6x5 plus 4x3 plus 2 to equal 105?
(9+8)x(7-6)x5+4(3+2)
How do you Substitute x equals y plus 3 into x plus 2y equals 9?
x = y+3 x+2y = 9 => x = 9-2y y+3 = 9-2y 2y+y = 9-3 3y = 6 y = 2 and x = 5
N plus 3 - 9 if n equals 15?
If you know that n = 15, substitute 15 for n and solve: n + 3 - 9 15 + 3 - 9 9
What is 9 plus 87 equals?
9 plus 87 equals 96.
What is 12 plus 9 equals?
12 plus 9 equals 21.
Does -9 plus 6 equals 3?
No! It equals 15, but 9-6=3.
If x equals 9 and y equals 6 what is 10x plus 7y?
Substitute the values of x and y in 10x + 7y, thus: 10x + 7y = 10*9 + 7*6 = 90 + 42 = 132
If 2 plus 3 equals 10 and 7 plus 2 equals 63 and 6 plus 5 equals 66 and 9 plus 7 equals 96 9 plus 7 equals what?
96
Solve this equation -9h - 6 plus 12h plus 40 equals 22?
The solution to this equation is that h is equal to -4. You can substitute this value for h into the equation to get -4 x -9 - 6 plus 12 x -4 plus 40 equals 22, or 36 - 6 plus - 48 plus 40 equals 22.
What is 9 plus 9 plus 9 plus 9 equals?
9+9+9+9 = 36
2 plus 3 equals 10 and 7 plus 2 equals 63 and 6 plus 5 equals 66 and 8 plus 4 equals 96 Then 9 plus 7 equals?
If I am correct, 9 plus 7 equals 112.
