What is the value of x and y in 8x equals 6y?
8x = 6y (8/6)x = y (4/3)x = y Let x = 3, 6, and 9, then y = 4, 8, and 12. So that for any value of x, you will find a correspoinding value for y.
If y varies directly as x and y is 6 when x is 72 what is the value of y when x is 8?
y is 2/3.
Which value of x satisfies both -9x 4y 8 and -3x y 4 given the same value of y?
If you mean: -9x+4y = 8 and -3x+y = 4 then the solutions are x = -8/3 and y = -4
Find the value of 2 numbers if their sum is 12 and their difference is 4?
x+y=12 x-y =4 x=12-4 =8 8+y=12 y=12-8 =4 so x=8 y=4 8+4=12 8-4=4
When x equals 8 and y equals - 4 find the value of 2x - y?
x = 8y = -42x - y = 2(8) - (-4) = 16 + 4 = 20
if y = 5x – 8 find the value of x if y = 7?
if y = 5x – 8 find the value of x if y = 7
if x = 3 and y = 8 then what is the value of x + y?

What is the y intercept for y equals x plus 8?
Add 8 to the x value, so f.e. If x=4, the y intercept = 4+8 =12 No, the y intercept is the value of y when the value of x = 0, so the y intercept of the equation is 8. In the general form y = mx + b, b will always be the y intercept.
Solve this equation using subtitution x plus y equals 10 and y equals x plus 8?
x+y = 10 and y = x+8 x+x+8 = 10 x+x = 10-8 2x = 2 x = 1 Substitute the value of x into the original equations to find the value of y: So: x = 1 and y = 9
What is the value of x and y in 8x equals 6y?
8x = 6y (8/6)x = y (4/3)x = y Let x = 3, 6, and 9, then y = 4, 8, and 12. So that for any value of x, you will find a correspoinding value for y.
If 4 multiplied by y eqeals x and x added by y eqeals 10 what is the value of x and y?

How do you solve 2x plus y equals 8 y equals -x plus 5 substitution method?
2x+y = 8 y = -x+5 Substitute y for -x+5 into the first equation: 2x+(-x+5) = 8 2x-x+5 = 8 x = 8-5 x = 3 Substitute the value of x into the original equations to find the value of y: x = 3 and y = 2
What is the value of y when x=8?
the value is 20
What is the x-value when y equals 8?
Since the relationship between x and y is not defined, x can have any value whatsoever.
When the value of y varies directly with x and y -16 when x -4. Find y when x 8?
y is 32.
If y varies directly as x and y is 6 when x is 72 what is the value of y when x is 8?
y is 2/3.
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
