2x plus 3y equals 13 3x minus y equals 3 x equals?
2x+3y=13 3x-y=3 x=2
What is the x value 2x-3y equals -15 x equals 4y?
If: 2x-3y = -15 and x = 4y Then: x = -12 and y = -3
What is the equation x equals 3y in standard form?
x = 3y x - 3y = 3y - 3y x - 3y = 3y - 3y x - 3y = 0
Solving each system using the substotution method 2x equals 3y x equals 3y-3?
2x=3yx=3y-32(3y-3)=3y substitution6y-6=3y distributive property3y=6 addition property of equalityy=2 multiplication(division) property of equalityx=3(2)-3 substitutionx=6-3x=3
Solving by subsitution x - 2y equals 0 4x - 3y equals 15?
x - 2y = 04x - 3y = 15From the first equation, x = 2y.SUBSTITUTING this value of x in the second equation,4*(2y) - 3y = 15 ie 8y - 3y = 15 or 5y = 15 so that y = 3and then, x = 2y gives x = 2*3 = 6Answer: x = 6, y = 3
What does X and Y equal in the equations 2X equals 3Y and 4X-3Y equals 12?
y = 4, x = 6
What does y equal for this x-3y plus 9 equals 0?
x-3y+9=0 So x+9=3y So x/3+3=y That means y= x/3+3 Of course you still don't know what y is, except in terms of x.
If 2x equals 3y and x does not equal 0 what is the ratio of x to y?
2x=3y The ratio of x:y is 3:2 as there are three xs in two ys.
2x plus 3y equals 13 3x minus y equals 3 x equals?
2x+3y=13 3x-y=3 x=2
What is the common point of these equations 2x plus 3y equals 12 and x - 3y equals -3?
(3, 2) because x = 3 and y = 2
What is the x value 2x-3y equals -15 x equals 4y?
If: 2x-3y = -15 and x = 4y Then: x = -12 and y = -3
What does 4x-3y equals 1 2x plus 3y equals 2 equal?
second equation x 2: 4x + 6y = 4 subtract first equation: 9y = 3 so y = 1/3 and x = 1/2
What is the slope of a line perpendicular to x - 3y equals 9?
x-3y = 9 -3y = -x+9 y = 1/3x -3 Perpendicular slope = -3
What is the equation x equals 3y in standard form?
x = 3y x - 3y = 3y - 3y x - 3y = 3y - 3y x - 3y = 0
How do you solve each system by substitution or addition 2y-x equals 3 and x equals 3y-5?
Add the two equations together. The x disappears. 2y - x = 3 + x = 3y - 5 ------------------------ 2y = 3y -2 Can you finish it from there?
What is the slope intercept form of the equation x-3y equals 3?
x-3y=3 is the same as -3y=-x+3 and now divide by -3 and you have y=(1/3)x-1 which is the slope intercept form.
What are slope intercepts for -x plus 3y equals 6?
-x + 3y = 6 3y = x 6 y = x/3 + 2 So slope = 1/3 and intercept = 2
