Q1-
A set of equations is given below: 

Equation H: y = −x + 2 
Equation J: y = 3x − 4 

Which of the following steps can be used to find the solution to the set of equations?
 −x = 3x − 4  
−x +2 = 3x 
−x + 2 = 3x − 4 
−x + 1 = 3x + 2

Answer 1

heyo!

Answer 2

Okay so do you know the steps to solving a system of equations?

Answer 3

I know them, but don't quite understand them.

Answer 4

so how are you used to solving these? There are two ways.

Answer 5

It looks like for this one it would be easier to cancel out

Answer 6

These are the steps I learned-
Substitution Method
Step 1: Isolate one variable in one equation.
Step 2: Substitute the expression from one equation into the other equation. 
Step 3: Solve for the unknown variable. 
Step 4: Substitute the value that you just found into one of the original equations to find the other variable. 
Step 5: Check your work on both equations using substitution.

Answer 7

Okay so one is already 3x so you would multiply the entire first equation by three so the other first term is -3x and it cancels out because 3x - 3x = 0

Answer 8

here one second

Answer 9

\[y = −3x + 6\]\[ y = 3x −4 \]\[y=2\]

Answer 10

Ok, I see what you did now

Answer 11

so how do I figure out which answer @~hellooo
