Is (1,6) a solution to this system of equations? 5x + y=11
2x + 3y= 20

x = 1

y = 6

Step-by-step explanation:

5x + y = 11 | ×3 |

2x + 3y = 20 | ×1 |

15x + 3y = 33

2x + 3y = 20

--

13x = 13

x = 13/13

x = 1

5x + y = 11

5(1) + y = 11

5 + y = 11

y = 11 - 5

y = 6

$450.00 for 6 weeks

or

$300

step-by-step explanation:

$200.00 for first week $50.00 x5 equals $250 plus $200 equals $450.00 for six weeks.

$200 for first week

$200 x 0.10 = $20

$20 x 5 = $100

$200 + $100 = $300
