Question

Will someone please help me slove this problem?
Use the elimination method to solve the system of equations.

5u+2v=-18
3u+v=-5

I have tried to solve this problem several times and have not gotten the correct answer please help. Thank you.

Answer 1

5u+2v=-18
3u+v=-5

Multiply second equation by two and subtract from the first equation.

6u+2v = -10

-u = -8

Multi[ply by -1.

Insert u value into the first equation to find v, then check by putting both values into the second equation.
