Question

Solve using elimination, graphing, or substitution:

4x - 3y= 1
y + 2x= 3

Answer 1

re arrange your second equation .. it would become. y= 3-2x
now put this value of y in your first equation and solve it...

Answer 2

elimination: 1. re-write y+2x=3
2. choose either x or y to eliminate
3. when eliminating one they have to be equal but opposite ex: 2x, -2x
4. so lets say ur eliminating the x and u make them equal a shown above. you then do the math for "y"

(im not done yet i also have to do the math lol)

Answer 3

5. after finding y you repeat to find x.

Answer 4

Ok I'm lost. What's with all the rearranging? :)

Answer 5

ok , y+2x = 3 isnt in the same form as as 4x-3y=1, so you have to change it to the same form as 4x-3y=1

Answer 6

Ok so it's

2x + y=3
4x - 3y=1 ??

Answer 7

yeah, and after u get that u can choose either the x or y to eliminate

Answer 8

Graphing was an option so.. here you go ^_^'
It has color

Answer 9

You can rearrange either equation but rearranging y+2x=3 for y is the easiest. y=3-2x you put that value for y in the first equation 4x-3y=1
This gives 4x-3(3-2x)=1
4x-9+6x=1
4x+6x=10
10x=10
x=1

put x=1 into the second equation y=3-2(1) which gives you y=1

now you can test if this is correct by putting the values of x and y into the first equation
4(1)-3(1)=1

Answer 10

@WilliamF
oh ur doing substitution , right?

Answer 11

@HELPKP Yeah

Answer 12

@e.cociuba substitution never stuck to me,i liked elimination but at least you has all three ways to solve the equation

Answer 13

i meant 'have'

Answer 14

Ok so which should I do than lol?

Answer 15

either one u do there're all right

Answer 16

don't ever call me a liar again

Answer 17

Well then y dont u explain y ur name went from Eric to Dylan suddenly.... Hmm?

Answer 18

i was adopied out of foster care

Answer 19
