A system of linear equations is shown below.
yulyashka [42]

Answer: No solution

Step-by-step explanation:

2m+4p=22

6m+12p=66

First, to choose one variable to simplified, I choose to find 1st equations in m form.

2m+4p=22

      2m=22-4p            [Subtract 4p from both side]

         m=22/2 - 4/2p  [Divide 2 on both side to find m]

         m= 11 - 2p

6m+12p=66          

6(11-2p)+12p=66          [Plug in the 11-2p in to m,according to the 1st equation]

66-12p+12p=66

The -12p has cancel with 12p, so it means that there is no solution

Levart [38]

Answer Step-by-step explanation:

Salesperson~A=11% of~67,530=\frac{11}{100} *67530=0.11

=0.11*67530=7,428.3

Salesperson~B= 8% of~85,740=\frac{8}{100}*85740= 0.08

=0.08*85740=6,859.2

7,428.3 > 6,859.2

Thus,~Salesperson~A~made~more~commission~than~Salesperson~B.
