Aset of equations is given below:

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? (1 point)

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.

Can someone explain the elimination method to me for this problem?
