Answer:
Y=-3x+5
Step-by-step explanation:
The first one i dont know srry
So first you want to find the price of all the magazines he bought which is 3.95 x 3 = 11.85.
then you are going to find out how much money he had left to spend on books which is 47.65-11.85=35.80
then you want to find how many books he bought with that money so you would take 35.80/8.95= 4
so he bought 4 books
Answer:
x = 7 and y = -2
Given:
x = 5y + 17 _____first equation
2x + 3y = 8 ____second equation
Steps:
2x + 3y = 8
<em>plug in x = 5y + 17 into second equation</em>
<em></em>
2(5y + 17)+3y = 8 [ open the brackets ]
10y + 34 + 3y = 8
10y + 3y = 8 - 34 [ collect and group terms ]
13y = -26 [ divide both sides by 13 ]
y = -2 [ final answer ]
solve for x:
x = 5y + 17
x = 5(-2) + 17
x = 7
