Question

2x + y = 8
x + y = 4
The lines whose equations are given intersect at.

A) (4, 0)
B) (0, 4)
C) all points on the line

Answer 1

do you know how to use elimination? or substitution?
you can use these methods to solve for the intersection of the lines

Answer 2

@Data_LG2 I'll give ya a medal to help.

Answer 3

let's eliminate the variable "y" first to solve for "x"
by subtracting the first equation to the second equation
can you do that for me?

Answer 4

2x + y = 8

-(x + y = 4)

x+0=4

x=4

x + y = 4

4+y=4

y=0

2x + y = 8

[(2)(4)]+0=8

8+0=8

8=8

(A) (4,0)???

Answer 5

Answer 6

looks like you're right! (^_^)

Answer 7

Awesome!!! Thanks, @Data_LG2

Answer 8

no problem :)
keep up the good work! @ihatealgebraplease

Answer 9

Would you mind helping with this problem @Data_LG2 3x + 2y = 5. 5x + 2y = 7.
Based on the given system of equations, which of the following is NOT true.


A) 2x = 2
B) 8x = 12
C) 4y = 4

Answer 10

same thing as you did before,
try to solve for x and y
if you already found this variables check out which one of the choices is true
for a, it says that x is equal to 1
b, x=3/2
c. y=1
