Equation E: c = 2d + 1

Equation F: c = 3d + 7

Which statement describes a step that can be used to find the solution to the set of equations?

Equation F can be written as c = 3 (c - 1) + 7.

Equation F can be written as c = 2 (c - 7) + 1.

Equation F can be written as d + 1 = 3d + 7.

Equation F can be written as 2d + 1 = 3d + 7.

As is the case with any two lines, we can say y=y or x=x when we are looking for solutions, as when there is a solution y=y and x=x. Since we can say that c=c, we can also say that:

2d+1=3d+7
