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?

Answer 1

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

Answer 2

hint: substitute one of the u = into one of the equations.

Answer 3

b?

Answer 4

no...
I'll give an example

Equation A: x = 4y+1
Equation B x = 2y+2
so one of the steps is to substitute one of the equations into the other . So I'll take my equation A which is x = 4y+1 and place it to equation B
so I should have
4y+1=2y+2

Answer 5

Oh. Then it's D?
