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?

Equation F can be written as 5b + 1 = 3b + 4.
Equation F can be written as b + 1 = 3b + 4.
Equation F can be written as a = 3(a − 1) + 4.
Equation F can be written as a = 5(a − 4) + 1.

Answer 2

First option is reasonable. If we do the first;
\[b = \frac{ 3 }{ 2 }\]
and
\[a = \frac{ 17 }{ 2 }\]
