₤5.60
using proportion, divide ₤4 by 5 to obtain the cost of 1 cake and multiply by 7 for the cost of 7
5cakes → ₤4
7cakes → ₤4 × = ₤5.60
The polynomial has two terms. The exponent of the first term is two. The exponent of the second term would be 1 because 5xy^1 is equal to 5xy.
Answer:
x = -1
y = -2
Step-by-step explanation:
The two equations are:
Substituting (2) in (1) we get:
∴ x = -1
Substituting the value of x in (2), we get
y = -1-1 = -2.
∴ y = -2
