What two numbers have a difference of 7 and a sum of 29?
Let's denote the two numbers as x and y. We know that x - y = 7 and x + y = 29. By solving these two equations simultaneously, we can find the values of x and y. Adding the two equations together, we get 2x = 36, so x = 18. Substituting x back into the second equation, we find y = 11. Therefore, the two numbers are 18 and 11.

What two numbers multiply to get 315 and add to get 52?
1) x*y=315 2) x+y=52 from 2, x=52-y, put into 1, y*(52-y) = 315 or y^2-52*y+315=0 delta= (-52)^2-4*1*315=1444 = 38^2 y = (52-38)/2 = 7 or y = (52+38)/2 = 45 then x = 45 or x = 45

How to Solve the system using substitution 3x plus 2y equals 7 y equals negative 3x plus 11?
Where is y in the first equation, you put its equivalent (=) -3x + 11 The first equation is then transformed into: 3x + 2*(-3x + 11) = 7. Then you get: 3x + (-6x) + 2*11 = 7 <=> -3x + 22 = 7 <=> 22 - 7 = 3x <=> 3x = 15 <=> x = 15/3 <=> x = 5. Then you substitute the x in the second equation by its equivalent so, (x = 5) y = -3*x + 11 <=> y = -3*5 + 11 <=> y = -15 + 11 <=> y = -4. x = 5. y = -4.

What are the values of the variables when the equations of y equals 2x plus k and y equals x squared -2x -7 meet each other at one distinct point?
If: y = x^2 -2x -7 and y = 2x +k Then: x^2 -2x -7 = 2x +K Transposing terms: x^2 -4x +(-7 -k) = 0 Using the discriminant formula: 4^2 -4*1*(-7 -k) = 0 => k = -11 Using the quadratic equation formula: x^2 -4x +4 = 0 => x = 2 By substitution: y = -7 Therefore the values of the variables are: k = -11, x = 2 and y = -7
Y divide 7 plus 6 equals 11?
y/7 + 6 = 11 Subract 6 from bot sides: y/7 = 11 - 6 = 5 Multiply both sides by 7: y = 5*7 = 35
The sum of two numbers is 38 and one tenth of the greater number equals one ninth of the smaller. Find the numbers?
1. (1/10)x=(1/9)y --> 2. (1/10)x/(1/9)=y --> 3. (9/10x)=y 4. Plug into other equation.x+y=38 4. x+9/10x=38 ----> 5. 1.9x=38 --> 6. x=20 7. Plug x into one of the original equaitons.7. 20+y=38 --> 8. y=18x=20,y=18
What is the answer to 2y plus 15 plus 7?
It is 2y + 22 = 2(y + 11)
What is y - 4 equals 7?
y=11
What is the equation of the line whose intercepts are x is 7 and y is 11 showing work?
Points: (7, 0) and (0, 11) Slope: 0-11/7-0 = -11/7 Equation: y-0 = -11/7(x-7) => 7y = -11x+77 Equation: y-11 = -11/7(x-0) => 7y = -11x+77
Two integers have a difference of -11 and a sum of -3 What are the integers?
Two integers (X & Y). X+Y=-3, X-Y=-11. x=-11+y --> (x)+y=-3 --> (-11+y)+y=-3 --> y=4 x=-11+4=-7 Hope that helps! Two integers (X & Y). X+Y=-3, X-Y=-11. x=-11+y --> (x)+y=-3 --> (-11+y)+y=-3 --> y=4 x=-11+4=-7 Hope that helps!
