Algebra.Com's Answer #46330 by funmath(2933)![]() ![]() ![]() You can put this solution on YOUR website! Solve each of the following systems by using either addition or substitution. If a unique solution does not exist, state whether the system is dependent or inconsistent. \n" ); document.write( "E1) 10x +2y = 7 \n" ); document.write( "E2) Y = -5x + 3 \n" ); document.write( "Let the y in E1=-5x+3: \n" ); document.write( "10x+2(-5x+3)=7 \n" ); document.write( "10x-10x+6=7 \n" ); document.write( "6=7 \n" ); document.write( "The variable disappeared and 6 does not = 7, therefore there is no solution and the system is inconsistent. \n" ); document.write( "Happy Calculating!!! \n" ); document.write( " \n" ); document.write( " |
