Question

A set of equations is given below:

Equation A: u = 4v + 1
Equation B: u = 3v + 5

Which of the following is a step that can be used to find the solution to the set of equations?

A. 4v + 1 = 3v
B. 4v = 3v + 5
C. 4v + 5 = 3v + 1
D. 4v + 1 = 3v + 5

Answer 1

D.
`4v + 1 = 3v + 5`

Explanation:

Equation A: v = 4v + 5

Equation B: v = 3v + 5

---------------------------------

4v + 1 = 3v + 5

-3v

---------------------------------

v + 1 = 5

-1 -1

---------------------------------

v = 4

---------------------------------

v = 4(4) + 1 = 17

v = 3(4) + 5 = 17

Thus, your answer is D. 4v + 1 = 3v + 5.
