Since x = -2
-2 = y + 4 2 (-2) - 3y
-y + 3y = 4 2(-2) +2
2y = (4 2(-2)) + 2
After that divide that by 2 to get Y.
Sorry but I do not know the space between 4 and 2x
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
