Question

Solve the following system of equations. Express your answer as an ordered pair in the format open parentheses a comma b close parentheses, with no spaces between the numbers or symbols. 3x+6y=3
2x-10y=44

Answer 1

Hi welcome to openstudy :)
So the problem gives use 2 equations
3x+6y=3 <---equation 1
2x-10y=44 <---equation 2
let's isolate x in the first equation so that we can solve by substitution
Can you please isolate the x? :)
3x+6y=3
Make sure you show the steps

Answer 2

3x+6y=3
-6y -6y
3x=3-6y
--------
3 3 3
x=1-2y
is that correct?

Answer 3

Good personally i would right it as -2y+1 means the exact same thing
x=-2y+1 <---equation 1
2x-10y=44 <---equation 2
Now we can solve by substitution equation 1 into equation 2
2(-2y+1)-10y=44
solve for y

Answer 4

2(-2y+1)-10y=44
-47+2-10y=44
+10y
-2
-4y=44+10y-2
--------------
-4 -4 -4 -4
y=-11-2.5y-.5

Answer 5

Im not sure what you did....
we get a hole number for the value of x

Answer 6

what do u mean

Answer 7

what was i supposed to do?

Answer 8

2(-2y+1)-10y=44
start by distribtuing the 2
2(-2y+1)

Answer 9

i did that which gave me
-4y+2

Answer 10

-4y+2-10y=44
combine like terms
-4-10=?

Answer 11

-14

Answer 12

good
−14y+2=44
subtract 2 from both sides what are you left with?

Answer 13

-16y=42???

Answer 14

wait or
-14y=42

Answer 15

Yes didive both sides by -14
y=?

Answer 16

y=-3.14
thats pi

Answer 17

42/-14=?

Answer 18

close enough lol

Answer 19

-3 my bad

Answer 20

good so y=-3
x=-2y+1
Plug -3 in place of y
x=-2(-3)+1

Answer 21

Solve

Answer 22

x=7

Answer 23

so my answer is (7,-3)

Answer 24

Good job :) so we have
x=7
y=-3
Correct
