Question

08.03)A set of equations is given below:

Equation A: y = x + 1
Equation B: y = 4x + 5

Which of the following steps can be used to find the solution to the set of equations?

x + 1 = 4x + 5
x = 4x + 5
x + 1 = 4x
x + 5 = 4x + 1

Answer 1

Both the x-expressions are equal to 'y'.

That will lead you to the solution.

Answer 2

k thanks

Answer 3

Thanks for what? Did you use that information? What did you conclude?

Answer 4

Well im not good at all with this kind of stuff so its very hard for me

Answer 5

That does not answer my question. What is your plan for solving this problem? What does my hint mean?

If x = y and if z = y, can we conclude that x = z?

Answer 6

yes
