Solve the system of equations by the methods of substitution x-2y equals 0 and 3x plus 2y equals 8?
Your answers are x = 2 & y = 1Original Equationsx - 2y = 03x + 2y = 8Solve for a variable (x)x = 2ySubstitute x with its equation3*(2y) + 2y = 86y + 2y = 88y = 8y = 1Solve for second variablex = 2*(1)x = 2Check your answer(2) - 2*(1) = 03*(2) + 2*(1) = 8
Y intercept of 2y equals -6x plus 8?
2y = -6x + 8 The y intercept occurs when x = 0 2y = 8 therefore y = 4
Simplify 3x plus 2y plus 2 equals 4y plus 4?
The equation can be simplified to show a value of Y in terms of X. 3X + 2Y +2 = 4Y + 4 3X + 2 = 2Y + 4 3X -2 = 2Y and 2Y = 3X - 2 means that Y = (3/2 X) -1
Is 3x plus 2y equals 8 a quadratic function?
3x + 2y = 8 2y=8-3x y=4-1.5x A quadratic has x^2 This is the equation of a line with negative slope.
Evaluate and simplify if possible 5x - 2y for x -7 and y - 3?
If x = -7 and y = -3 then 5(-7) -2(-3) = -29
-2y equals x plus 8?
-2y=x+8 is the answer
Answer of x plus 2y-9 equals 4?
x + 2y - 9 = 4 can be rewritten as x + 2y = 13, but this is as far as you can simplify it because you have two unknowns and one equation.
How do you solve 8 plus x2y?
i don't get that if it is 2xy +8 or 8 + 2xy then you can't solve or simplify it any further if it were 8 x 2y then you time the 8 by the 2 to get 16y
Simplify 3x - 2y plus 9 plus 9y - x?
3x-2y+9+9y-x = 2x+7y+9
What are ordered pairs for x plus 2y equals 8 and 2x plus y equals 7?
Rearrange the first equation: x=8-2y. Plug in this value of x into the second equation: 2(8-2y)+y=7. Simplify: 16-4y+y=7. -3y=-9. y=3. Plug this value of y into the first equation: x+2(3)=8. Solve for x: x=8-6. x=2. The answer is {2,3)
Solve this equation using subtitution x plus 2y equals 7 and 2x plus y equals 8?
x + 2y = 7 So x = 7 - 2y Substitute this value for x in the second equation which then is: 2(7 - 2y) + y = 8 Simplify: 14 - 4y + y = 8 -3y = -6 y = 2 Put this value of y back into the first equation: x + 2*2 = 7 ie x + 4 = 7 x = 3
What is x plus 2y equals -8 in slope intercept form?
-6
What is the x-int and y-int of -x plus 2y equals 8?
-x+2y=8 Rewrite 2y-x=8 Add x to both sides 2y=x+8 Divide both sides by 2 y=0.5x+4 As can be seen by writing the equation in slope intercept,the y intercept is 4 Going back to the 2y=x+8,substituting 0 for y gives 0=x+8.The x intercept is -8.
Is 4y-2x equals 0 a linear equation?
Let's simplify it ... (4y-2x) = 0 = (2y -x ) = 0 2y = x y = x/2 Yes, it is linear.
How do you simplify -5(x plus 2y)-3x plus 8y plus 5?
-5(x + 2y) -3x + 8y + 5 = -5x -10y -3x + 8y + 5 = -8x -2y + 5
How do you Rewrite x - 2y 8 using function notation?
If you mean: x-2y = 8 then it is y = 0.5x-4.
Can anyone solve x plus 2y equals 8 and 3x-2y equals 8 as a simultaneous equation and show their working?
x+2y=8 Here you must add the expressions (2y - 2y = 0) 3x-2y=8 4x=16 Now you are left with a multiple of x so you can simply divide by 4 x=4 on both sides of the = 4+2y=8 Now you substitute x=4 into one of the original equations to find y 2y=4 y=2 Hope this helped.
