Answer:
x=−1, y=−1
Step-by-step explanation:
Solve for x in the first equation.
x=−2−y
10x+3y=−13
Replace all occurrences of x with −2−y in each equation.
−20−7y=−13
x=−2−y
Solve for y in the first equation.
y=−1
x=−2−y
Replace all occurrences of y with −1 in each equation.
x=−1, y=−1
Find the inverse of the first function. then plug in the answer to x. afterwards solve it and the answer is 1, so its a
Two divided into five (2/5) would be the answer.
The reason why, is because 2/5 is just another way of saying your going to divide 2 into 5
