Question

A set of equations is given below:

Equation C: y = 4x + 8
Equation D: y = 4x + 2

Which of the following best describes the solution to the given set of equations?

A. No solution
B. One Solution
C. Two solution
D. Infinitely many solution

Answer 1

y = 4x + 8 <---e1
y = 4x + 2 <--e2
Both of these equations tell us what y equals we can use substitution to solve the problem
Plug e1 into e2 (either way you will get the same answer)
4x+8=4x+2
Solve for x

Answer 2

x=4?

Answer 3

How did you get that?

Answer 4

I subtracted 4x and 4x and then I did 8/4

Answer 5

4x-4x=0

Answer 6

8=0x+2
subtract 2 from both sides
8-2=?

Answer 7

u got it

Answer 8

so you don't divide ?

Answer 9

Well you really can't
6=0
How many solutions are there ?

Answer 10

no solution?

Answer 11

Well done :)
