Question

How many solutions will this system of equations have?

y = 3.5x - 3.5
y = -3.5x + 3.5

No solution

Infinite solutions

One solution

Two solutions

Answer 1

need help

Answer 2

well try to solve it :D

Answer 3

i did and i got it mixed some how with no solution and one solution

Answer 4

y = 3.5x - 3.5
y = -3.5x + 3.5

add up the equation then u would have

2y=0
y=0

then
y = 3.5x - 3.5
0= 3.5x - 3.5
so =1


so there is a solution which is (1,0)

Answer 5

and it unique , so only one solution

Answer 6

got it ?

Answer 7

ya i think so

Answer 8
