Algebra.Com's Answer #711460 by greenestamps(13200)![]() ![]() You can put this solution on YOUR website! For a system of two linear equation to have an infinite number of solutions, the two equations must represent the same line. Algebraically, that means each equation is a multiple of the other. \n" ); document.write( "In the given pair of equations, the coefficient of y in the second equation is 12 times the coefficient of y in the first equation (2/3 times 12 equals 8), and the coefficient of x in the second equation is 12 times the coefficient of x in the first equation (1/4 times 12 equals 3). So the constant in the second equation has to be 12 times the constant in the first equation: 2*12 = 24. \n" ); document.write( "Answer: a = 24 \n" ); document.write( " |
