How do you solve y equals y equals 2x-1 y equals 5x-13?

y = 2x -1 y = 5x -13 So: 5x -13 = 2x -1 5x -2x = 13 -1 3x = 12 x = 4 and by substituting y = 7


What are the zeros of the graph of the function y equals 2x plus 5x-12?

y = 2x + 5x - 12 = 7x - 12 So the zero is 12/7 = 1.7143 (approx)


Y equals 5x plus 18 y equals 2x plus 9?

5x+18 = 2x+9 5x-2x = 9-18 3x = -9 x = -3 and y = 3


How do you add 2x plus 3y equals 18 in 5x-y equals 11?

How do you add 2x plus 3y equals 18 in 5x-y equals 11


5x-2y plus 3z-2x-y-4z equals?

5x-2y+3z-2x-y-4z=3x-3y-z


2x plus 6 equals -6 5x plus 7y equals 1?

if: 2x + 6 = -6 then: 2x = -12 x = -6 if: 5x + 7y = 1 then: 5(-6) + 7y = 1 7y = 31 y = 31/7


Solve the following system of equations using substitutions 2x plus 3y equals -1 and 5x-2y equals -12?

First get y in terms of x: 5x-2y=-12 ----- -2y=-12-5x ------ y=6+(5/2)x Sub into other equation: 2x+3y=-1 ---- 2x+3(6+(5/2)x)=-1 Solving for x gets: x= -2 Sub into other equation: 5x-2y= -12 --- 5(-2)-2y= -12 --- y=1 So x= -2, and y= 1


2x-y equals 4 and y equals 5x-7?

Your answer is x = 1 & y = -2Given Equations:2x-y=4y=5x-7Using SubstitutionSubstitute y for 5x-7 to simplify the equation to only 1 variable.2x-(5x-7)=4Simplifya. 2x-5x+7=4b. -3x=-3c. x=1Solve for yPlug your x into the y equationy=5*(1)-7y=-2Check your answersPlug your variables into the multi-varible equation2*(1)-(-2) = 4


What is 2x plus 3y equals -1 5x-2y plus -12 using substitution?

x = -2 and y = 1


Write an equation of a line that has the same slope as 2x - 5y equals 12 and the same y-intercept as 4y plus 24 equals 5x?

You need to put these equations into the slope-intercept form (y = mx + b) so you can read the slope and y-intercept.2x - 5y = 12 4y + 24 = 5x-5y = -2x + 12 4y = 5x - 24y = 2/5x - 12/5 y = 5/4x - 6slope m = 2/5 y-intercept = -6New equation with the same slope as the first equation and the same y-intercept as the second equation:y = 2/5x - 6Or you could also write it as:5y = 2x - 30 if you multiplied each term by 5, or 2x - 5y = 30 if you rearranged the terms to be in the same order as the first equation was.


What lines would these be 2x plus 5y equals 6 and 5x-2y equals 8?

2X + 5Y = 6 5Y = - 2X + 6 Y = - 2/5X + 6/5 ----------------------------------and 5X - 2Y = 8 2Y = - 5X + 8 Y = - 5/2 + 4 ------------------- Look like intersecting lines, though not perpendicular
