The expressions "xx" and "xy" suggest that you might be referring to two equations involving the variables x and y. If you meant to write the equations as (y = xx) (or (y = x^2)) and (y = xy) (or (y = x \cdot y)), they can be rewritten into a system of equations. However, without clearer definitions of these expressions, it's difficult to provide a precise system. Please clarify the equations for a more accurate response.
What else can I help you with?
Solve this equation using addition method x subtract y equals 6 and 3y equals x plus 22?
x - y = 63y = x + 22you need to solve these equations simultaneously.first get all your x's and y's on the same side.x - y = 63y - x = 22if you add these two equations together, the x's will cancel as one is positive and the other negative.x - y + 3y - x = 22 + 62y = 28y = 14then substitute y is 14 into one of the original equations to find xx - 14 = 6x = 20
What is the value for x in the following systems of equations x-y equals 5 2x plus y equals 7?
x - y = 52x + y = 7 (use the substitution method)y = x - 52x + y = 7 (substitute x - 5 for y into the second equation)2x + y = 72x + x - 5 = 73x = 12x = 4Thus x = 4 satisfies both the equations of the system.
What is the value of x for the equations x-y equals 120 and x plus y equals 150?
x-y = 120 x+y = 150 add equations: 2x = 270 x = 135 y = 15
What is the answer to the systems of equations x minus y equals 10 x plus y equals 4?
X - Y = 10 X + Y = 4 -------------------+ ( add them ) 2X = 14 X = 7 ----------find Y in one of the equations; top looks good 7 - Y = 10 - Y = 3 Y = - 3 ---------------check both equations for consistency 7 - (- 3) = 10 7 + 3 = 10 10 = 10 ------------checks in top 7 + (- 3) = 4 7 - 3 = 4 4 = 4 ------------checks and is consistent (7, - 3) ( the answer )
What is a method used for solving systems of equation in which one of the equations is substituted into another?
It is called substitution. Solve one of the equations for a single variable and substitute it into the other. x+y=10 y=10-x 2x-y=-4 2x-(10-x)=-4 2x-10+x=-4 3x-10=-4 3x=6 x=2 x+y=10 (2)+y=10 y=8
What is graphing method?
In systems of equations, the graphing method is solving x and y by graphing out the two equations. x and y being the coordinates of the two line's intersection.

What is 12x-5y-20 using the systems of equations with substitution?
To solve the expression (12x - 5y - 20) using systems of equations with substitution, you would first need to have a system of equations that includes variables (x) and (y). You can solve one of the equations for one variable in terms of the other, then substitute that expression into (12x - 5y - 20). After substituting, you can simplify the expression to find its value based on the specific values of (x) and (y) from the original system of equations.
Two numbers sum to 50 their difference is 16 what are two equations for this problem?
x + y = 50 x - y = 16 --------------- (add the two equations to solve for x) 2x = 66 x = 33 then substitute x into one of the above equations to get y = 17
What are simultaneous equation in maths?
Simultaneous equations are where you have multiple equations, often coupled with multiple variables. An example would be x+y=2, x-y=2. To solve for x and y, both equations would have to be used simultaneously.
What is the common point of these equations x plus y 10 x - y 6?
Without any equality signs the given terms can't be considered to be equations but if you mean x+y = 10 and x-y = 6 then the value of x is 8 and the value of y is 2 and both equations intersect at (8, 2) on the Cartesian plane.
What is the x and y of x-y equals -1 and -x plus y equals -1?
