What algebraic property is 8 equals x and x equals y?
Transitive property: If 8 equals x and x equals y, then 8 equals y.
What the results of x plus 2y-2x-y equals x equals?
The result of the equation x + 2y - 2x - y equals x simplifies to y - x.
If x equals 3 and 3 equals y then?
x=y
What is the solution to x plus y equals 8 y equals x?
x=4 y=4
What is x plus 32 equals 55?
x + 32 = 55 x = 55 - 32 x = 23
How do you solve x times 7 percent equals y when x plus y equals 55?
To solve this system [x*7% = y], [x+y = 55], first solve for y in the second equation: y = 55-x. Then, substitute y in the first equation for 55-x: x*7%=55-x. Since x*7% is 1.07x, we can say that: 1.07x = 55-x. Then, add x to both sides to get: 2.07x = 55. Divide by 2.07, and x = 25.57. Finally substitute 25.57 for x in the second equation to get: 25.57+y = 55 , and y = 24.43. Therefore, x = 25.57, and y = 24.43
How do you solve x times 7 percent equals y plus x equals 55?
So if I'm reading it correctly: x * (7%) = y + x = 55. So you have two different expressions, both equal to 55. x * (7%) = 55. Change 7% to 0.07, then divide both sides by 0.07 --> x = 5500/7 y + x = 55, with x = 5500/7 from above. y + 5500/7 = 55 --> y = 55 - 5500/7 = -5115/7 So x = 5500/7, or approximately 785.71 ; y = -5115/7, or approximately -730.71
What is the x-intercept of y equals -3x-5?
2
What is the answer for y equals x?
x equals y
X plus 6y equals 55 -x plus 6y equals 53?
Presumably this is a simultaneous question in which you're asked to find the values of x and y. x+6y = 55 -x+6y = 53 Adding both equations: 0+12y = 108 Divide both sides by 12 to find the value of y: y = 9 Substituting y = 9 into the original equation will enable you to find the value of x: x = 1 and y = 9
What algebraic property is 8 equals x and x equals y?
Transitive property: If 8 equals x and x equals y, then 8 equals y.
Find two numbers whose sum is 55 and whose difference is 21?
Let the numbers be x and y x+y=55 and x-y=21 Now since x-y=21 x=21+y. Plug that into the first equation. 21+y+y=55 or 21+2y=55 so 2y=55-21=34 and y =17 Now since 17+x=55, we immediately see that x=38.
What is y equals x plus 2 when x equals -1 and y equals 5?
If [ y = x + 2 ], then x is not -1 when y = 5.If [ y = x + 2 ],then when x = -1, y = 1,and when y = 5, x = 3.
If y equals one-forth x and x equals -12 then what is y?
x equals -12 and y equals 1/4 of -12, so y = -3.
If x equals 3 and 3 equals y then?
x=y
What the results of x plus 2y-2x-y equals x equals?
The result of the equation x + 2y - 2x - y equals x simplifies to y - x.
If x and y are inversely proportional and x equals 13 when y equals 12 w is x when y equals 24?
26.
