2x-4 equals 12 what is the value of x?
2x - 4 = 12Add 4 to each side:2x = 16Divide each side by 2:x = 8
2x - 6 equals 4 then what is the value of x?
2x - 6 = 4 2x = 4 + 6 = 10 x = 10/2 = 5 ∴ x = 5
What is the Value of 3x - 4 if 2x plus 1 equals -5?
2x + 1 = -5 so 2x = -6 so that x = -3 Then 3x - 4 = 3*(-3) -4 = -9 - 4 = -13
-2x plus 4y -4 find the y?
The value of y in the equation -2x plus 4y -4, is 1 plus x/2.
What is the value of x in 6x plus9 equals -3?
6x + 9 = -3 6x/3 + 9/3 = -3/3 2x + 3 = -1 2x + 3 - 3 = -1 - 3 2x = -4 2x/2 = -4/2 x = -2
Substituiotion method to find the value of y y equals 2x plus 5 x plus y equals 4?
y = 2x+5 x+y = 4 Substitute the value of y into the second equation: x+2x+5 = 4 x+2x = 4-5 3x = -1 Divide both sides by 3 to find the value of x: x = -1/3 Substitute the value of x into the original equations to find the value of y: x = -1/3 and y = 4 and 1/3
If 2x - 6 equals 4 then what is the value of x?
2x -6 = 4 then 2x = 4 +6 x=10/2 = 5
What is the value of x if 2x-6 equals 4?
5
What is the value of y equals 2x when x equals 4?
y=8 y = 2x y = 2(4) <-- substitute 4 for x y = 8 <-- this is your answer
What is the value of the x in 2x plus 4 equals 3x?

2x-4 equals 12 what is the value of x?
2x - 4 = 12Add 4 to each side:2x = 16Divide each side by 2:x = 8
2x - 6 equals 4 then what is the value of x?
2x - 6 = 4 2x = 4 + 6 = 10 x = 10/2 = 5 ∴ x = 5
2x-y plus 4 equals 0?
2x-y+4=0... what are you actually trying to find?
If x equals 3 and y equals 4 what is the value of 2x plus y - 1?
x = 3 y = 4 2x + y - 1 = (6) + (4) - 1 = 9
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
Solve this system of equation using substitution 2x plus 6y equals 24 and 3x-2x equals 24?
Solve this system of equation using substitution 2x plus 6y equals 24 and 3x-2x equals 24 ?Improved Answer:2x+6y = 243x-2x = 24 => x =24Substitute the value of x into the top equation to find the value of y:48+6y = 246y = 24-486y = -24y = -4So: x = 24 and y = -4
