Question

A set 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?

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.

Answer 1

I think it might be c

Answer 2

no remember the last question
y = y expressed differently same thing

Answer 3

ok

Answer 4

start with c = 3d + 7

then replace c with what it is also equal to

Answer 5

They would both equal to each other so it would be D

Answer 6

yes 2d + 1 = 3d + 7

Answer 7

Thank you
