Presumably this is a simultaneous equation in the form of:
x = 8-2y
y-x = 4
Which is the same as:
2y+x = 8
y-x = 4
Add both equations together:
3y = 12.
So y will equal 4.
Substitute the value of y into the original equations to find the value of x:
So: x = 0 and y = 4

Use the Substitution method to solve the system of equationsx plus y equals -4 and x - y equals 2?
x + y = -4x - y = 2x - y = 2x + y - y = 2 + yx = 2 + yx + y = -42 + y + y = -42 + 2y = -42 - 2 + 2y = -4 - 22y = -62y/2 = -6/2y = -3x = 2 + yx = 2 - 3x = -1The solution of the system is (-1, -3)
What is the solution of y equals 0 and x equals y plus 2?
y = 0x = y + 2plug 0 in for yx = 0 + 2x = 2
If x-1 is a solution to the equation yx plus 5 what is the value of y?
If you mean y = x+5 and x is -1 then y = 4
What is the equation of a line that is perpindicular to a line that's equation is yx 4?
If you mean: y = x+4 then the perpendicular equation can be y = -0.5x+4
Y to the power x times y to the power x?
yx * yx = y2x.Using the law of exponents, we add the 2 exponents, getting you 2x rather than just 'x'.
If xy equals x or yx equals x what is y?
xy = x ÷x y = 1
If Y' equals 2xy plus x to power 3 what is y equal to?
Assuming y' is dy/dx, y = x^4/4 + yx^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
If x plus y equals 3 and yx equals 2 then y is equal to what?
If x+y = 3 and y times x = 2 then y = 1.
Use the Substitution method to solve the system of equationsx plus y equals -4 and x - y equals 2?
x + y = -4x - y = 2x - y = 2x + y - y = 2 + yx = 2 + yx + y = -42 + y + y = -42 + 2y = -42 - 2 + 2y = -4 - 22y = -62y/2 = -6/2y = -3x = 2 + yx = 2 - 3x = -1The solution of the system is (-1, -3)
What are the x and y intercepts of -2x equals 20 plus 5y?
-2x = 20 + 5y-2x - 20 = 5y-2/5x - 4 = yX Intercept = (-10,0) or -10Y Intercept = (0,-4) or -4
What is the solution of y equals 0 and x equals y plus 2?
y = 0x = y + 2plug 0 in for yx = 0 + 2x = 2
What is xy plus x plus 3y plus 3?
The problem to solve is: xy+x+3y+3 Multiply y and x Multiply the y and x Multiply y and x The y just gets copied along. The x just gets copied along. The answer is yx yx x*y evaluates to yx x*y+x evaluates to yx+x Multiply y and 3 Multiply y and 1 The y just gets copied along. The answer is y y 3*y evaluates to 3y The answer is yx+x+3y x*y+x+3*y evaluates to yx+x+3y The answer is yx+x+3y+3 x*y+x+3*y+3 evaluates to yx+x+3y+3 ---- The final answer isyx+x+3y+3----
What is the x-intercept of the graph of yx-3?
yx-3 is not an equation, and it has no graph.
Xy plus yx equals 545 what is the value of x and y?
xy and yx are identical so you have 2xy = 545 ie xy = 272.5. Possible answers 5 and 54.5, 10.9 and 25 etc
Which expression is not equivalent to 8 x 2 y?
82y 16x are both not equal to the given expression.
If x-1 is a solution to the equation yx plus 5 what is the value of y?
If you mean y = x+5 and x is -1 then y = 4
