X - Y = 2
When X = 3 you have 3 - Y = 2
Moving Y to RHS: 3 = Y + 2
Moving 2 to LHS: 1 = Y

What are the points of intersection between the equations of 3x -5y equals 16 and xy equals 7?
If 3x -5y = 16 and xy = 7 then by combining both equations into a single quadratic equation and solving it then the points of intersection are at (-5/3, -21/5) and (7, 1)
What is a 2 step equation that equals 3?
1+3x=10
Solve using substitution x minus y equals 2 and x plus y equals -4?
-2
What is the answer to this equation y equals -2x plus 3?
y=-2x+3 is an equation. It does not have an answer. If the question is "what if y=0?" then the answer is x=3/2.
What is the value of x in the equation 8x plus -2 equals 10?
3/2
What is an equation using five 2's that equals 3?
2+2+2+2+2-7 This is an equation that uses 5 2's yet equals 3.
What are the points of intersection between the equations of 3x -5y equals 16 and xy equals 7?

What is a 2 step equation that equals 2?
(1+3)/2
The only integer n where n equals xy equals yx and x does not equal y?
This gives us the equations: n = xy = yx x != y (Note that for this example, the != stands for not equal to similar to some programming languages.) xy always equals yx due to the communtative property of multiplication. So there are actually an infinite number of answers. Some are given below: 6 = (2)(3) = (3)(2), 2 != 3 12 = (3)(4) = (4)(3), 3 != 4
Suppose y varies inversely with X use the information to find K and choose the equation of variation. X equals 7 and y equals 3?
xy = K so K = 21
Is 2 plus 3 equals 5 an equation?
no not really
What is the point-slope equation of the line with a slope equals -4 and a point of -2 3?
Which of the following is the point-slope equation of the line with a slope equals -4 and a point of -2 3?
How do i solve this equation . C-2 - 4 equals 3?
You would do it it by oppisites. 3+2+4=9 which equals C.
Solve using substitution x minus y equals 2 and x plus y equals -4?
-2
What is a 2 step equation that equals 3?
1+3x=10
What are the solutions to the simultaneous equations of x squared plus xy plus y squared equals 7 and 2x plus y equals 1?
I suggest you solve the second equation for one of the variables, then replace that in the first equation.Another Answer:-x2+xy+y2 = 7 and 2x+y = 1Merging the two equations together in terms of x will result in a quadratic equation of:3x2-3x-6 = 0Divide all terms by 3:x2-x-2 = 0When factored: (x+1)(x-2) = 0So: x = -1 or x = 2Solutions: when x = -1 then y = 3 and when x = 2 then y = -3
