Answer:
False
Step-by-step explanation:
2x + y = 0
Try (1, -2)
2(1) + (-2) = 0
2 + (-2) = 0
0 = 0
The solution works on the first equation.
-x + 2y = 5
-(1) + 2(-2) = 5
-1 - 4 = 5
-5 = 5
The solution does not work in the second equation.
Answer: False
wait i will take screen shot please bran-list
The system of equation which represent the scenario is;
x + y = 42
x + y = 420.13x + 0.18y = 6.66
<h3>Simultaneous equation</h3>
let
- number of 13 cent stamps = x
- number of 18 cent stamps = y
- Total cost of the stamps = $6.66
- Total number of stamps = 42
x + y = 42
x + y = 420.13x + 0.18y = 6.66
Therefore, the equation which represent the problem is;
x + y = 42
0.13x + 0.18y = 6.66
