If your system is
x - y = 120
x + y = 150
I would use elimination. Adding the two equations together gives us
2x = 270
and dividing by two tells us that x = 135. Plug x back into either equation to find y:
x + y = 150
135 + y = 150
y = 15
So x = 135 and y = 15.

When y is inversely proportial to square of x .K the constant is equals 120 so find x when y is equal to x?
sorry, it is wrong the answer is : y=k/x2(square) {when y = x we will write y as x and leave x2(square) alone. like this: x=120/x2(square) x multiply by x2(square) is x3(cube) so cube root of 120 = x so x is 4.93
Does the equation x plus y equals 41 define y as a function of x?
Both. If you look at it like this: y=41-x you say x is independent and y is dependent of x (i.e. y is a function of x) For x=41-y you say y is independent and x is dependent of y (i.e. x is a function of y)
What is Y x plus 5 Y 6?
The answer to Y x plus 5 Y 6 is Y(x+5Y5).One possible solution to y x plus 5 y 6 is Y(x+5Y5).
What is the value of y when the value of x is 3?
It depends on the relationship between x and y.
What is the value of x and y in x plus y equals -7 x-y equals 1?

What is the value of x for the equations x-y equals 120 and x plus y equals 150?
x-y = 120 x+y = 150 add equations: 2x = 270 x = 135 y = 15
What is the y value of x - y equals 120 x plus y equals 150?
15 (x = 135)
What is the value of y for the equations x-y equals 120 and x plus y equals 150?
15
What is X plus y equals 120 x plus y equals 150?
It's an inconsistent pair of equations, for which there is no solution.
Use addition or substitution to find the value of x for this set of equations for x - y equals 120 x plus y equals 150?
X = 135 and y = 15 Solved by addition and substitution
What is 120 x 1.25?
150
2 numbers can be added to equal 7 and multiplied to equal -120?
Assume that the two numbers are represented by 'x' and 'y': x+y=7 and xy= -120 As x+y=7, re-arrange the formula so that x=7-y Now substitute for x: (7-y)y = -120 7y-y2= -120 7y-y2+120 = 0 y2_7y-120 = 0 (y-15)(y+8) = 0 Therefore y = 15 or -8, and so putting back into the original equation, when y=15, x = -8, and when y= -8, x = 15
What are 2 numbers whose sum is 120 and whose difference is 50?
We have the numbers x and y. x+y=120 x-y=50 2x=170 x=85 y=35
150 volts is what percent of 120 volts?
150 / 120 = 1.251.25 x 100 = 125answer:125%150 volts is 125 percent of 120 volts.
What is 20 percent off of 150 pounds?
150 x (1 - 20/100) = 150 x 0.8 = 120 Therefore, 20 percent off 150 pounds is 120 pounds.
What is 150 minus 20 percent?
150 - 20% = 150 x (1 - (20/100)) = 150 x 0.8 = 120
Find x-intercept and y-intercept of the line given the equation 8x-2y-120?
8x - 2y-120 = 0 subsitute the x with zero to find the y intercept 0x - 2y-120=0 -2y-120=0 -2y=120 y=60 substitue the y with zero to find the x intercept 8x-120=0 8x=120 x=120/8 x=15 lol hopefully i did this rite... sorry if i didnt XD i have a coordinate geometry test tomorrow... lol
