How many solutions does this system of equations have 2x-3y equals -14 4x-6y equals -28?
The equations are identical in value, ie the second is merely twice the first...
What is the solution of x equals 6y-4 and x equals -2y plus 28 using substitution?
x=6y-4x=-2y+28Substitute (6y-4) for x in the second equation and solve for y:6y-4=-2y+288y=32y=4Then solve for x:x=6(4)-4=20(20,4)
What is the ordered pair of 3x plus 6y equals 36 3x-6y equals 0?
3x + 6y = 363x - 6y = 0 add both equations6x = 36x = 63x - 6y = 03(6) - 6y = 018 - 6y = 018 = 6y3 = yThe solution point is (6, 3).
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.
What is 3x plus 6y equals 42 and -7x plus 8y equals -109 please use elimination and show work Thanks?
4(3x+6y = 42) 3(-7x+8y = -109) Multiply all terms in the top equation by 4 and in the bottom by 3: 12x+24y = 168 -21x+24y = -327 Subtract the bottom equation from the top remembering that a minus from a minus is equal to a plus: 33x = 495 Divide both sides by 33: x = 15 Substitute the value of x into the original equations to find the value of y: Therefore: x = 15 and y = -1/2
-15 plus 6y equals 13?
-15 + 6y = 13 6y = 13+15=28 y=28/6=4.66 or 4 and 2/3
What is the Sum of three x minus y equals twelve?
What is 3x-6y=12

What is the ordered pair of 4x plus 6y equals 62 -6x plus 6y equals -18?
4x + 6y = 62-6x + 6y = -18 Multiply this equation by -1 the result will be_______________4x + 6y = 626x - 6y = 18_______________ Equation 1 + Equation 2 the result will be10x = 80 ----> X=8Put the value of X in one of the Equations above to find the value of yand so Y=5
6y equals 8-9 plus 6y Find the value of y?
Two ways to see this: 6y=8-9+6y 6y=6y-1 No answer here 6y= 8-(9+6y) 6y+(9+6y)=8 12y+9=8 12y=-1 y= -(1/12) or -0.08333...
What is the answer to 8y squared plus 6y minus 2?
The answer depends on the value of y. For example, when y = 0, 8y2 + 6y - 2 = -2 when y = 1, it is 12
What is x equals 4y-2 and x equals 6y plus 8?
By definition: 4y-2 = 6y+8 4y-6y = 8+2 -2y = 10 y = -5 and by substituting this value into the equation x = -22
4x plus 6y equals 62 and -6x plus 6y equals -18?
4x+6y=62 -6x+6y=-18 what is the ordered pair
If 6 times y minus 1 plus 8 equals 32 what is y?
6y-1+8=32 y=4 1/6 Here's the steps- 6y-1+8=32 6y+7=32 6y=25 y=4 1/6
What is the solution of x equals 6y-4 and x equals -2y plus 28 using substitution?
x=6y-4x=-2y+28Substitute (6y-4) for x in the second equation and solve for y:6y-4=-2y+288y=32y=4Then solve for x:x=6(4)-4=20(20,4)
Solve by the elimination method x plus 6y equals 19 -x plus 6y equals 17?
(A) x + 6y = 19 (B) -x + 6y = 17 (A)+(B): 12y = 36 so that y = 3 Substituting this value of y in (A), x + 18 = 19 so x = 1.
What does 4x plus 6y equals 24 7x plus 6y equals 9?
It does nothing! 4x + 6y = 24 7x + 6y = 9 Subtracting the first equation from the second gives: 3x = - 15 so that x = -5 Substituting the value of x in the first equation gives -20 + 6y = 24 so that 6y = 44 and so y = 22/3 or 71/3
