X plus y equals 4 2x plus y equals 10?
2x+y = 10 x +y = 4 Subtract bottom equation from top equation: x = 6 Substitute the value of x into the equations to find the value of y: x = 6 and y = -2
X plus y is 11 and product of x and y is 30 so what is the value of x and y?
Two solutions:x = 5 and y = 6, orx = 6 and y = 5.
2x plus y equals 25 x plus y equals 14?
2x + y = 25 x + y = 14 Subtract second equation from the first: x = 11 Substitute this value of x in the second equation: 11 + y = 14 ie y = 3
If x equals a-b y equals b-c z equals c-a then the value of x plus y plus z x plus y plus z is?
x + y + z = 0 x = a - b, y = b - c, z = c - a, therefore a - b + b - c + c - a = ? a - a + b - b + c - c = 0
What is the value of x(5 plus y) if x4 and y2?
If x = 4 and y = 2 then 4(5+2) = 28
What is y equals plus x in c plus plus?
y += x means the value y+x is first calculated, and the resulting value is then assigned to y. It is equivalent to y = y+x
If x plus 2 equals y and y equals 16 what is the value of x plus y?
x = 14
If y equals x plus 1 what is the value of x?
y - 1
What is the min value of 1 by x plus 1 by y plus 1 by z equal30 when x y and z are positive and x plus y plus z equal 30?
(1/x) + (1/y) + (1/z) is a minimum value when x=y=z=10. Symmetry gives either maximum or minimum value.
What value of b makes y equals x plus b the same as y x What does this value means?
If: y = x+b then y-x = b
What is the value of y in y equals -27x plus 75?
It depends on the value of 'x'. 'y' can have as many different values as 'x' can.
What is the sum of x plus y?
That depends on the value of x and y. As an expression, "x + y" can't be simplified.
If x plus 2 equals y what is the value of x-y plus y-x?
x + 2 = y x - y + y - x = 0, even though what is y equivalent. Are you sure, you are looking for something else?
What is the value of y in x equals -6 and x plus y equals 0?
y = 6
If x and y are prime numbers and 3x plus 4y equals 143 then what is the value of x plus y?
x + y = 17 + 23 = 40
What is the value of x plus 2y equals 10 and 3x-y plus 2?
y=2.5 and x=5
What is the y value of x - y equals 120 x plus y equals 150?
15 (x = 135)
