Algebra.Com's Answer #292022 by Gogonati(855)![]() ![]() You can put this solution on YOUR website! Solution: From the first linear equation x=2-4y Substitute this value of x in the second equation; 6(2-4y)+5y=-12 This is a first grade equation. Solving it we find out the value of y. 12-24y +5y=-12: -19y=-24; y=24/19 To find out the x value substitute y=24/19 in the first equation; x=2-4(24/19); x=-58/19. \n" ); document.write( "Answer: the solution for this system linear equations is the ordered pair (-58/19,24/19). \n" ); document.write( " |
