Answer 1

Solve the system of equations by substitution. What is the solution for x?

2x + y = 1
4x + 2y = −1
x = 0 x = 2 There is no x value, as there is no solution.
x can be any value, as there is an infinite number of solutions.

Answer 2

ello love :D need some help?

Answer 3

yes plz

Answer 4

okay so we need to solve for x using the substitution method, correct?

Answer 5

yes

Answer 6

okay so we solve for y in one equation like so:

2x+y=1

subtract 2x from both sides:

y=-2x+1

Answer 7

then we substitute that for y in the other equation:

4x+2(-2x+1)=-1

follow me?

Answer 8

yes I get it although I think my answer would be "B" then but plz explain more to me

Answer 9

alright so we simplify this equation by solving for x:

4x+2(-2x+1)=-1

think you could simplify the equation for x? hint: PEMDAS

Answer 10

yea I got it now so the answer is b lol thnxs

Answer 11

alright :) no problem
