Question

Solve using the substitution method 3x + 2y = 3, 9x − 8y = −2

Answer 1

well what do u know about complementary angles?

Answer 2

So, the two angles together are 90 degrees. Can you turn the info you have into an equation?

Answer 3

Well the Question that is being asked is that what are the two complementary angles.... and they give us that one part equals4x-2 and the other one equals x

Answer 4

and beacuse when you add complementary angles it equals to 90

Answer 5

Your equation should look like

Answer 6

Liza2, yes

I just don't know how to brake it down....

I have so far this:
<1=4x-2
<2=x
<1+<2=90 deg
and from there am stuck

Answer 7

\[4x-2 + x =90\]

Answer 8

I dont know what to do next

Answer 9

Can you isolate "x" using the equation @CouldntFindAGoodName just gave you?
4x - 2 + x = 90
Because once you've isolated x, you can figure out the measurements of both angles

Answer 10

Both angles equal 90 so u just add the angles and get 4x-2 +x =90

Answer 11

Then you isolate the x

Answer 12

But beforew you isolate the x u add like terms

Answer 13

SO it would be like 4x+x -2=90 which equals ---> 4x-2 =90

Answer 14

am confused, so

how would I add, is it like this:
x+(4x-2)=90
5x-2=90

Answer 15

* 5x-2=90

Answer 16

Then you isolate the x

Answer 17

awesome I have that so far CouldntFindAGoodName

Answer 18

First you add 2 to both sides of the equation

Answer 19

how would I isolate the x thou?

Answer 20

First add 2 to both side of the equation

Answer 21

like (5x-2) +2 =90 +2 ----> to get 5x=92

Answer 22

Then from there to isolate the x you divide the 5 on both side like (5x)/5=92/5

Answer 23

then u are left with x=18.4

Answer 24

and for your x value would equal 18.4

Answer 25

then you just plug in your x value for your two complementary angles

Answer 26

1< 4x-2 ---> 4(18.4)-2
2< x----> 18.4

Answer 27

xD no problem XD
