What is the value of x in the equation 4x - 20 equals -4?
4x - 20 = -44x = 16x = 4
How do you solve the system of equations -2x plus y equals -1 - 4x plus 3y equals 27?
Presumably this is a simultaneous equation in the form of: -4x+3y = 27 -2x+y = -1 Multiply all terms of the bottom equation by 2: -4x+3y = 27 -4x+2y = -2 Subtract the bottom equation from the top equation remembering that a - - is equal to a + Meaning that -4x - -4x = 0 and 27 - -2 = 29: So y will = 29 Substitute the value of y into the original equations to find the value of x Therefore: x = 15 and y = 29
What is the value of x in the equation 4x 2 equals 2x 34?
If the missing signs are pluses, x = 16.
What is the value of x in the equation 3 over 4x plus 2 equals 5 over 4x-6?
If the questions asks: (3)/(4x+2) = (5)/(4x-6) then x = -(7/4)
Find an equation of variation where y varies directly as x and y equals 28 when x equals 7?
4x= y
You have to find the value of x in the sum 4x-6 equals 2?
change the equation around 4x-6=2 becomes 4x=2+6
4x - 2y equals -2 4x plus 5y equals 33?
First arrange this simultaneous equation in the form of: 4x+5y = 33 4x-2y = -2 Subtract the bottom equation from the top equation remembering that a - - is equal to a +: 7y = 35 Divide both sides by 7 to find the value of y: y = 5 Substitute the value of y into the original equations to find the value of x: So: x = 2 and y = 5
What is the value of x in the equation 4x - 20 equals -4?
4x - 20 = -44x = 16x = 4
What is the value of y in the equation 4x plus 5y equals -6?
-2
What is 4x-6 equals 2x-2?
It is an equation and the value of x is 2
4x-y equals 32 4x plus 5y equals -16?
Presumably this is a simultaneous equation question in the form of: 4x-y = 32 4x+5y = -16 Subtract the bottom equation from the top equation remembering that a -- is equal to a + so 32--16 is +40 and that -+5y-y is -6y: -6y = 48 Divide both sides by -6 to find the value of y: y = -8 Substitute the value of y into the original equations to find the value of x: So: x = 6 and y = -8
Which property is 4x equals 24?
4x = 24 is not any property. It is an equation which is true for some value of x, not for others.
What value of x satisfies the equation 4x plus 2 equals 22?
5.0
What is the value of x in the equation 4x plus 5 equals 20?
x = 3.75
Solve by the substitution method 4x-5y equals -8 4x plus 40 equals y?
4x-5y = -8 4x+40 = y => y = 4x+40 Substitute the value of y into the top equation: 4x-5(4x+40) = -8 4x-20x-200 = -8 4x-20x = 200-8 -16x = 192 Divide both sides by -16 to find the value of x: x = -12 Substitute the value of x into the original equations to find the value of y: Therefore: x = -12 and y = -8
What 6x plus 3 equals 4x plus 11?
It is an equation and the value of x is 4
What is 4x plus 2x plus 2 equals 26?
It is an equation and the value of x is 4
