Solve this system of equation using substitution 2x plus 6y equals 24 and 3x-2x equals 24 ?Improved Answer:2x+6y = 243x-2x = 24 => x =24Substitute the value of x into the top equation to find the value of y:48+6y = 246y = 24-486y = -24y = -4So: x = 24 and y = -4


Solve using substitution x plus y equals 3 and y equals 9?

Since the second equation is already solved for "y", you can replace "y" by "9" in the other equation. Then solve the new equation for "x".


5x plus 3y plus z equals -29 solve this system of equation?

To solve an equation with three unknowns, x, y and z, you require 3 independent equations.


Solve using substitution x minus y equals 2 and x plus y equals -4?

-2


Solve this equation using substitution 3x plus 2y equals 2 and -2 plus y equals 8?

From second equation: y = 8 + 2xSubstitute for y in first equation: 3x + 16 + 4x = 2ie 7x = -14ie x = -2 and y = 4


Solve this equation using substitution 5x plus y equals 5 and 3x plus 2y equals 3?

From first equation: y = 5 - 5xSubstitute for y in second equation: 3x + 10 - 10x = 3ie -7x = -7ie x = 1 and y = 0


Solve this equation using substitution 5x plus y equals 1 and 3x plus 2y plus 2?

It is not possible to do so because the question contains one equation (5x + y = 1) and one expression (3x + 2y + 2). An expression cannot be solved.


How so you slove y equals 6x and 2x plus 3y equals -20 by using the system of substitution?

To solve a system of equations using substitution you solve one of the equations for one of the variables then substitute that into the other equation to solve for the other variable. For example. y = 6x 2x + 3y = -20 The first equation has already been solved for y. So, you simply substitute that into the second equation. 2x + 3(6x) = -20 2x + 18x = -20 20x = -20 x = -20/20 = -1 Now you have solved for x. You can substitute your answer for x back into the first equation to solve for y. y = 6x = 6(-1) = -6 Putting it all together... x = -1 y = -6
