Solve the system using elimination

x = 5

y = 1/4

Step-by-step explanation:

Let a = 1/x

     b = 1/y

Then the equations are

(1)        10a - 4b = -14     and     (2)    5a + 8b = 33     Multiply equation (2) by -2

         -10a - 16b = -66

                  -20b = - 80

                        b = 4                         5a + 8(4) = 33

                                                          5a + 32 = 33

                                                                  5a = 1

                                                                    a = 1/5

a =  1/x = 1/(1/5)                   x = 5

b = 1/y = 4                           y = 1/4

step-by-step explanation:

m = 2e

m = 2 so 2 = 2e

1 = e

in problems involving proportions, we can use cross products to test whether two ratios are equal and form a proportion. to find the cross products of a proportion, we multiply the outer terms, called the extremes, and the middle terms, called the means.
