Question

I don't get this question---->

A set of equations is given below:

Equation E: a = 5b + 1
Equation F: a = 3b + 4

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


A. Equation F can be written as 5b + 1 = 3b + 4.
B. Equation F can be written as b + 1 = 3b + 4.
C. Equation F can be written as a = 3(a – 1) + 4.
D. Equation F can be written as a = 5(a – 4) + 1

Answer 1

How do you know? i need proof not just an answer..

Answer 2

@Michele_Laino plz help me with this.

Answer 3

if we apply the elimination method, then we can write this:
\[5b + 1 = 3b + 4\]

Answer 4

we put the equations together?

Answer 5

yes! Since both quantities:
\[5b + 1,\quad 3b + 4\]
are equal to the same quantity \(a\), then we can equate them each other
