Question

How many solutions does this system have?
2x+y=3
6x=9-3y

a.1
b. none
c.infinite
d.2

Answer 1

2x+y=3
6x=9-3y

first equation --> y = -2x+3

second equation ----> 3y = -6x+9
y = -2x +3

the two equations are the same
what would be the solution for a system of identical equations ?

Answer 2

im thinking c?

Answer 3

correct it's c

Answer 4

which cannot describe a system of linear equations?

a. no solution
b. exactly 2solutions
c. infinite solutions
d. exactly 1 solution

Answer 5

linear equations represent straight lines
do you know what is the intersection of two straight lines ?

Answer 6

two solution?

Answer 7

how many points of intersection ?

Answer 8

1

Answer 9

yeah
so there is one solution for a system of linear equations

Answer 10

so d

Answer 11

yes

Answer 12

it was exactly two solutions
