y = 2x + 3, 2y = 4x + 6 The system of equations has no solution(s).

The two lines have the same slope of 2 and are parallel to each other. There is no intersection/solution.

What is the solution set of the following system of equations?
5x - 3y - 10 = 0
x + y - 7 = 0
**Weegy:** To solve 5x - 3y - 10 = 0 and x + y - 7 = 0 , first move all numbers to the right side of the equation to get 5x - 3y = 10 and x + y = 7. [ The simplest method is substitution, from the second equation we get x = 7 - y, so 5 * (7 - y) - 3y = 10, solving for y we get y = 3.125 so x = 7 - 3.125 = 3.875. - See more at: ] **User:** What is the resulting equation when the expression for y in the second equation is substituted into the first equation?
3x + y = 1
y = 6 - 4x
**Weegy:** 3x + y = 1
3x + (6 - 4x) =1
3x + 6 - 4x =1 ............3x - 4x + 6 = 1.......-x + 6 = 1 The first choice... **User:** 1/2x + 1/3y = 3
Which of the following equations is equivalent to the given equation?
**Weegy:** FOIL (First Outside Inside Last)
= 2x(2x) + 2x(-3y) + (-3y)(2x) + (-3y)(-3y)
= 4x^2 + (-6xy) + (-6xy) + (9y^2)
= 4x^2 - 12xy + 9y^2
**User:** 1/2x +1/3y = 3
Which of the following equations is equivalent to the given equation?
3x + 2y = 3
2x + 3y = 18
3x + 2y = 18
**Weegy:** 3x + 2y = 18 **User:** What is the result of adding the system of equations?
2x + y = 4
3x - y = 6
x = 2
x = 10
5x = 10 **Weegy:** .) 2x + y = 3 2.) x - 2y = -1 If equation 1 is multiplied by 2 and then the equations are added, the result is

6x + y = 4

5x + y - 7 = 0

system determinant = 6(1) - 1(5) = 6 - 5 = 1

5x + y - 7 = 0

system determinant = 6(1) - 1(5) = 6 - 5 = 1
