(2.6 x 105)(1.9 x 10-2)

John used linear combination to solve the system of equations shown. he did so by multiplying the first equation by -3 and the second equation by another number to eliminate the x-terms. what number did jonas multiply the second equation by? 4x-6y=23x+5y=11

Solve for x and y: 217x + 131y = 913; 131x + 217y = 827

Find the values of the variables and the lengths of the sides of this kite.
