## anonymous one year ago A set of equations is given below: Equation A: y = x + 1 Equation B: y = 4x + 5 Which of the following steps can be used to find the solution to the set of equations? x + 1 = 4x + 5 x = 4x + 5 x + 1 = 4x x + 5 = 4x + 1

here we can apply the elimination method, so we can write: $\Large \begin{gathered} x + 1 = y = 4x + 5 \hfill \\ \hfill \\ x + 1 = 4x + 5 \hfill \\ \end{gathered}$

I still don't don't get it I mean I know I got to subtract from both sides

4. Michele_Laino

no, please, we have these two equations: $\Large\begin{gathered} y = 4x + 5 \hfill \\ y = x + 1 \hfill \\ \end{gathered}$

5. Michele_Laino

now the left sides are equal each other

6. anonymous

okay

7. Michele_Laino

then also the right sides have to be equal each other

8. Michele_Laino

so we can write: $\Large x + 1 = 4x + 5$

can you help me with 2 more test there only 5 questions each and ill give you meadls

another reasoning is: $x + 1 = y$ and $y = 4x + 5$ then if we apply the transitive property of equality, we get: $x + 1 = 4x + 5$

ok!
