Question

x + 2y = 10
2x +3y = 16

Answer 1

you need to eliminate one of the variables

Answer 2

i know but i need help working it out

Answer 3

subtract 2y from the left side of the first equation so it becomes x=-2y+10

Answer 4

make sense?

Answer 5

no like show me how like draw it out

Answer 6

Okay so that turns into
x=-2y+10
2x+3y=16

Answer 7

Now you plug in the first equation for x in the second one like so:
2(-2y+10)+3y=16

Answer 8

Now distribute.

Answer 9

Y=4

Answer 10

Not quite.
-4y+20+3y=16
-y+20=16
-y=-36
y=36

Answer 11

cause when you distrubte it is
-4y=20=3y+16

Answer 12

Not exactly. Look at my last post.

Answer 13

oh

Answer 14

So now that you know y=36, plug it into the first equation.

Answer 15

how

Answer 16

x+2(36)=10
x+72=10
x=-62
So your coordinates are (-62,36)
