Gavin and his 3 friends total 4 people. If they are to share equally in the 1/3 pound of cake, they must
... divide 1/3 by 4, or multiply 1/3 by 1/4. Therefore each friend gets 1/12 of cake.
Answer:
first of all the formula
y = mx+c
where m is slope and c is y-intercept.
now substitute the values-
y = 2x - 5
(for the slope here is 2 and the part where the line intercepts y axis is -5
therefore
y = 2x-5
The answer is 4!!!!!!!!! :)
x = -3
So to figure this out we can readjust the equation to make it easier to solve
is equal to 
From here we can just subtract 9 from both sides and we get our answer!

Answer:
Let 2x + y - 10 = 0 be equation (a).
Let x - y - 5 = 0 be equation (b).
Make y the subject in equation (b):

Substitute for y in equation (a):

Find y in any equation of your choice:
