Answer:
x =-1
y =-1
Step-by-step explanation:
to solve this system of equation, using substiution method
3x-4y=1 ........................ equation 1
x=2y+1 ............................ equation 2
subbstitute for x into equation 1
3x-4y=1 ........................ equation 1
3(2y + 1) - 4y = 1
6y + 3 -4y = 1
2y + 3 = 1
collect the like terms
2y = 1- 3
2y= -2
divide both sides by the coefficient of y which is y
2y/2 = -2/2
y = -1
put the value of y =-1 into equation 2
x=2y+1 ............................ equation 2
x = 2(-1) + 1
x = -2 + 1
x = -1
therefore x =-1 y = -1
Answer:
Step-by-step explanation:
(-7 - 1)/(6 + 2) = -8/8 = -1
y - 1 = -1(x + 2)
y - 1 = -x - 2
y = -x - 1
Answer:
66 pieces of candy.
Step-by-step explanation:
First I set up the equation: (c/6)-4 = 7
c represents the candy she started with.
6 represent when she split the candy
4 is the number of pieces she has eaten
7 is the number of pieces she has left
after setting up the equation, you want to add four to the other side to get 11
c/6 = 7+4 --> c/6 = 11
Then you want to multiply by 6 to get ride of the fraction to get a total of 66 pieces of candy.
c = 11 x 6 --> c = 66
