Solve the system -10=-2y+x 6y=3x+11

belka [17]

Answer: No Solutions exist

Step-by-step explanation:

We have the following system of equations

$-10=-2y+x$

$6y=3x+11$

Rewriting the second equation we have:

$-11=-6y+3x$

Now we multiply the first equation by -3 and add it to the second equation

$30=6y-3x$

$-11=-6y+3x$

---------------------------------

$19=0$

Equality is not satisfied. Then the system has no solution
