Question

Solve for x in the first equation, then solve the system using substitution. Write your answer as (x, y) 2x-6y=14, 4x-y=9'

Answer 1

Solve for x in the first equation, then solve the system using substitution. Write your answer as (x, y) 2x-6y=14, 4x-y=9'

Answer 2

change second equation to y=4x-9 it would be easier

Answer 3

then substitute that y into the first equation to get 2x-6(4x-9)=14 then distribute

Answer 4

now you have 2x-24x+54=14
combine like terms to get -22x+54=14
isolate the variable by subtracting 54 from both sides
now you have -22x=-40
divide both sides by -22
and your answer should be x=-40/-22=1.818181...

Answer 5

(1.8181,1.7272)
