[rough raven]

Anyone know where I can find practice problems like this questions exactly like this one I know it seems like I got it down but I feel like I need to practice a bit more to really make sure I remember it when the exam comes around

[candid narwhal]

Isn't this just solving systems of equations using 2x2 matrices

[pale saddle]

literally make any 2 random equations and solve them using cramers rule (what ur doing in the ss)

[rough raven]

Yeah

[rough raven]

Yeah but how will I know it’s correct

[pale saddle]

put the acquired values of x and y into the equation...

[rough raven]

Oh well I’ll get back to that tommorow I moved on to vectors just for tonight

[wispy warren]

make up 2 equations of 2 variables for example:

1. 3x - 2y = 4
2. 7x + 5y = -3

Solve them using your method, so the coefficient matrix would be something like:
3 -2 | 4
7 5 | -3

You can check your answer by using Wolframalpha.com and typing:
Solve: 3x - 2y = 4, 7x + 5y = -3

Hope this helps.
