Define system of linear equation in 2 variables?
4x + 2y = 6
What is the y-intercept for the linear equation 3x - 2y 18?
At the y-intercept, x=0 .-2y = 18y = -9
Simplify 6x - 2x - y6x - 2x - 2y 4x - 2y?
6x-2x-6xy-2x-2y4x-2y=2x-2y-14xy
What is substitution in algebra?
Substitution is used in Systems of Linear Equations. When you have two equations, such as y=3x+1 and 2y+5=9x+1, then substitution can be used. 2y could be substituted with 2(3x+1). You would have now the equation 6x+2=9x-1, which is more solvable.
What is the y-intercept in this linear equation 2y - 4x -12?
If you mean: 2y = -4x-12 then y = -2x-6 and -6 is the y intercept
What is the slope of the equation 2y equals 6x minus 8?
2y = 6x - 8y = 3x - 4========m(slope) = 3=========
How do you solve 2y minus 6x equal negative 8?
2y - 6x = -8 You have two unknowns and only one equation. In the absence of any other information, this equation cannot be solved. What can be done is to make each unknown the subject of the equation. 2y = 6x - 8 y = 3x - 4 6x = 2y + 8 3x = y + 4 x = (y + 4)/3
What is the standard form of the equation of the conic section given below x2-y2-6x-2y 60?
Assuming the equation is x2 - y2 - 6x - 2y = 60this is equivalent tox2 - 6x + 9 - y2 - 2y - 1 = 60 + 9 - 1= (x - 3)2 - (y + 1)2 = 68Assuming the equation is x2 - y2 - 6x - 2y = 60this is equivalent tox2 - 6x + 9 - y2 - 2y - 1 = 60 + 9 - 1= (x - 3)2 - (y + 1)2 = 68Assuming the equation is x2 - y2 - 6x - 2y = 60this is equivalent tox2 - 6x + 9 - y2 - 2y - 1 = 60 + 9 - 1= (x - 3)2 - (y + 1)2 = 68Assuming the equation is x2 - y2 - 6x - 2y = 60this is equivalent tox2 - 6x + 9 - y2 - 2y - 1 = 60 + 9 - 1= (x - 3)2 - (y + 1)2 = 68
What is the slop-intercept of -6x equals 2y-120?
-6x = 2y - 120 -2y -2y -2y - 6x = -120 +6x +6x -2y = 6x - 120 -2y/-2 = 6x/-2 - 120/-2 y = -3x + 60
What is the solution of 6x-2y equals 22?
6x - 2y = 22Solve for x:6x = 2y + 22x = 1/3y + 11/3Solve for y:-2y = -6x + 22y = 3x - 11You can not simplify the equations further without having one of the variables solved, or having more than 1 equation (such as a system)
Solve linear equation 2y equals 3x-4?
2y-3x=4
Linear equation examples?
6x+5k=12
Is 6x plus -7 a linear equation?
-1
What equation is the same as y equals 3x plus 1?
2y = 6x+2
Is 4x plus 2y equals 3 a linear?
Yes, it is a linear straight line equation.
How do you solve 6x-4y equals 54 -9x plus 2y equals -69 using substitution?
-9x + 2y = -69 So 2y = 9x - 69 The other equation can be written as 6x - 4y = 54 or 6x - 2*2y = 54 Substituting for 2y gives 6x - 2*(9x - 69) = 54 6x - 18x + 138 = 54 12x = 84 x = 7 and then 2y = 9x - 69 = 9*7 - 69 = 63-69 = -6 so that y = -3
What is the x-intercept for this linear equation 6x - y 9?
-3
