Question

Find the value of Q in the following system so that the solution to the system is:

{(x,y) : x-3y = 4}
x-3y=4
Qx-6y=8

Answer 1

Q=2

Answer 2

how did you get that answer? @ask1709

Answer 3

ok i looked at it and i saw that since its a system, the equations are the same. so, if you look at the equations, u see that the second equation is just the same as the first on but it is expressed 2 times larger

Answer 4

-3y*2=-6y

Answer 5

4*2=8

Answer 6

so the answer would be Q=8?

Answer 7

no it would be 2

Answer 8

since 1*2=?
