What is the value of x and y in x plus y equals -7 x-y equals 1?
-6
What is the y intercept for x plus y equals 5?
the Y in the sentence X plus Y equals 5 is Y=3 or 2 if the X is 2 or 3
What does x equal if y 2x 5?
y=2x-3 y=-x-3
What is 5x - 3y -7x plus 2y plus 3x?
5x - 3y -7x + 2y +3x = (5-7+3)x + (-3+2)y = x - y
What is the value of y when the value of x is 3?
It depends on the relationship between x and y.
What are the two integers whose sum is -3 and whose difference is 7?
x+y=-3 x-y=7 If we take the 2nd equation from the first we get: (x+y)-(x-y)=-3-7 2y=-10 y=-5 Sub into 1st equation x+(-5)=-3 x=2 Numbers are 2 and -5
X-y equals 5 2x plus y equals 7 answer?
x - y = 5 + 2x + y = 7 => 3x + 0 = 12 => 3x = 12 => 3x/3 = 12/3 => x=4 x-y=5 2x+y=7 =>4-y=5 =>2(4)+y=7 =>y=4-5 =>8+y=7 =>y=-1 =>y=-1 So, the answer would be x=4 and y=-1
Evaluate and simplify if possible 5x - 2y for x -7 and y - 3?
If x = -7 and y = -3 then 5(-7) -2(-3) = -29
X - y z when x -3 y -7 z 5?
-32
What the answer to this elimination x-y equals 7 and x plus y equals 3?
x = 5, y = -2
X plus y equals 3 and x-y equals 7?
10
Work out 2x equals y plus 7 and x-2 equals y simultaneous equation?
2x = y + 7 x - 2 = y substitute the y from the second equation into the first: 2x = x - 2 + 7 2x = x+5 x = 5 --> y = 5 - 2 y = 3
If x equals 7 and y equals 2x plus 3 what is 5x plus y?
If: x = 7 Then: y = (2*7)+3 = 17 And: 5x+y = (5*7)+17 = 52
How do you do y-73(x-4)?
If you mean: y -7 = 3(x -4) then y = 3x -5
X-y equals 8 and 2x plus y equals 7?
x=5 y=-3
Find and equation of the line containing the given pairs -7-3and -2-9?
Let (x1, y1) = (-7, -3) and (x2, y2) = (-2, -9).First, let's find the slope m:m = (y2 - y1)/(x2 - x1) = (-9 - -3)/(-2 - -7) = (-9 + 3)/(-2 + 7) = -6/5(y - y1) = m(x - x1) The point-slope form.y - -3 = -6/5(x - -7)y + 3 = -6/5(x + 7)y + 3 = -(6/5)x - 42/5 add (6/5)x and subtract 3 at both sides;y + (6/5)x = - 42/5 - 3(6/5)x + y = -57/5 The general formula.
How do you simplify y equals 2x-5 and 4x-y equals 7?
y = 2x-5 4x-y = 7 => y = 4x-7 2x-5 = 4x-7 2x-4x = 5-7 -2x = -2 x = 1 Therefore by substituting: x = 1 and y = -3
