Solve the system of equations 2x + y = -1.5 y = 3.50 + 15

1 answer:

6 0

So first y = 3.50 + 15 = 18.5
Next 2x + y = -1.5
2x = -1.5 -y
2x = -1.5 - 18.5 = -20
x = -20/2 = -10
So
x = -10
y = 18.5

b/c we can substructure 5cd and 3dc b/c it doesn't matter if the place of cd and dc change. what I mean if 5 ×3=15 and it is the same with 3×5=15 both of the product are the same but, if it is - and ÷ it wil be wrong for example 5-3=2 but 3-5= -2
