Question

y = –x + 2
y = 3x – 1
what is the solution of the system

Answer 1

y = –x + 2

3x - 1 = –x + 2 ... plug in y = 3x - 1


now solve 3x - 1 = –x + 2 for x

Answer 2

what do you get when you solve for x

Answer 3

3 right?

Answer 4

3x-1=-x+2


3x=-x+2+1


3x+x=2+1


4x=2+1


4x=3


x = ???

Answer 5

0.75

Answer 6

or x = 3/4

Answer 7

now use either equation to find y

Answer 8

can you set it up for me or show me how to set it up?

Answer 9

y = -x + 2 ... first given equation

y = -3/4 + 2 ... plug in x = 3/4

y = ???

Answer 10

1.25?

Answer 11

or 5/4

Answer 12

so

x = 3/4, y = 5/4

Answer 13

in decimal form

x = 0.75, y = 1.25

Answer 14

wow thank you !
