In order to find the value of a variable, it needs to be in an equation. For example:
2x=4
In order to solve for two variable you need to have two equations. For example:
2x+y=3
3X-5y=7
You are missing key information necessary to find a solution.

What is 13x 2y -10x-7y?
If you mean: 13x+2y-10x-7y then it is an algebraic expression that can be simplified to 3x-5y
3x - 7y equals 36 and y equals 3x?
1) y - 7y = 36 -6y = 36 y = -6 We know that, y = 3x -6 = 3x x= -2 Conclusion, y= -6, x = -2
If 3x equals 7y-2 and 9y equals 4x plus 1 Then what is the value of x and y?
3x = 7y - 2 (subtract 3x and 7y to both sides of the first equation)9y = 4x + 1-7y = -3x - 2 (multiply by 4 each term of both sides of the first equation)9y = 4x + 1 (multiply by 3 each term of both sides of the second equation)-28y = -12x - 827y = 12x + 3 (add both equations)-y = -5 (multiply by -1 both sides)y = 53x = 7y - 2 (substitute 5 for y)3x = 7(5) - 23x = 33 (divide both sides by 3)x = 11Thus, the solution of the given system of the equations is x = 11 and y = 5.
Solve for y -3x plus 6y equals 12?
y-3x+6y=12 7y=3x+12 y=3x/7 +12/7
3x-7y equals 14 what is the slope of the line given?
Where an equation is presented in this form then convert it to the standard slope intercept format of y = mx + c. The value of m is the slope. 3x - 7y = 14 7y = 3x - 14 y = 3/7x - 2 The slope is therefore 3/7.
What is 13x 2y -10x-7y?
If you mean: 13x+2y-10x-7y then it is an algebraic expression that can be simplified to 3x-5y
What is the y-intercept in this linear equation 7y plus 3x - 21 equals 0?
7y+3x-21 =0 7y = -3x+21 y = -3/7x+3 The y intercept is 3
Solve 3X plus 7Y equals 14 for Y?
3x + 7y = 14Subtract 3x from each side:7y = -3x + 14Divide each side by 7:y = -3/7 x + 2
What is the answer to simplify 5x-6y-2x-y?
The simplified expression is 3x - 7y.
Factor 21-7y plus 3x-xy?
21-7y+3x-xy7(3-y)+x(3-y)
3x - 7y equals 36 and y equals 3x?
1) y - 7y = 36 -6y = 36 y = -6 We know that, y = 3x -6 = 3x x= -2 Conclusion, y= -6, x = -2
If 3x equals 7y-2 and 9y equals 4x plus 1 Then what is the value of x and y?
3x = 7y - 2 (subtract 3x and 7y to both sides of the first equation)9y = 4x + 1-7y = -3x - 2 (multiply by 4 each term of both sides of the first equation)9y = 4x + 1 (multiply by 3 each term of both sides of the second equation)-28y = -12x - 827y = 12x + 3 (add both equations)-y = -5 (multiply by -1 both sides)y = 53x = 7y - 2 (substitute 5 for y)3x = 7(5) - 23x = 33 (divide both sides by 3)x = 11Thus, the solution of the given system of the equations is x = 11 and y = 5.
3x plus y equals 5 and 4x-7y equals -10?
3x+y=5(4x-7y)=-10 3x+y=20x-35y=-10 -3x -3x y=17x-35y=-10 -y -y 17x-36y=-10 sorry but that's as far as i could get :(
What is the y intercept of 3x-7y 8?
do you mean: 3x-7y=8 1. you have to get this equation set to "y=" form, so add 7y to both sides. 3x=7y+8 2. now subtract 8 on both sides 7y=3x-8 3. get "y" by itself, by dividing by 7 on both sides. y=3/7x -8/7 4. now find your "y intercept" formula y=Mx+B, "B" equals your "y intercept." -8/7 5. answer
What is the y-intercept of the graph of the equation 3x-7y equals 8?
Put in this form. Y = mX + c3X - 7Y = 8- 7Y = - 3X + 8Y = (3/7)X - 8/7===========Y intercept = - 8/7-----------------------
Solve for y -3x plus 6y equals 12?
y-3x+6y=12 7y=3x+12 y=3x/7 +12/7
If T equals 3x plus 7y what is T when x equals 4 and y equals 6?
T = 3x + 7y; x = 4; y = 6T = 3x + 7y (substitute 4 for x, and 6 for y)T = 3(4) + 7(6) = 12 + 42 = 54
