A set of equations is given below:

Equation A: c = 2d + 1
Equation B: c = 3d + 5

Which of the following is a step that can be used to find the solution to the set of equations?


2d + 1 = 3d + 5
2d = 3d + 5
2d + 1 = 3d
2d + 5 = 3d + 1

Respuesta :

2d+1=3d+5.
If both equations equal c, then both equations can be equal to each other.

Answer:

The correct option is 1.

Step-by-step explanation:

The given set of equations is

Equation A: c = 2d + 1

Equation B: c = 3d + 5

Using equation A and equation B, equate the value of c.

[tex]2d+1=3d+5[/tex]

[tex]1-5=3d-2d[/tex]

[tex]-4=d[/tex]

The value of d is -4. So the value of c is

[tex]c=2d+1=2(-4)+1=-7[/tex]

The equation 2d+1=3d+5 is used to find the solution to the set of equations, therefore the correct option is 1.
