Question

Determine the number of solutions the system of 4(x + 2) = y + x and y = 2x + 6.
A) No solution
B) One solution
C) Infinite solutions
D) Impossible to determine

Answer 1

you can do it a little matrix and solve

Answer 2

explain plz

Answer 3

4x+8=y+x
3x-y=-8
-2x+y=6

add the 2nd equation to the 1st. so x=-2
if x=-2 then y=2

so one solution

Answer 4

ty

Answer 5

it makes sense because both are equations of a line. as long as they are not parallel and they are linear (meaning exponents to the power of 1 or 0) then there is only one point at which they intersect.
