Question

Find the measures of the angles, given that x+y=40.(Hint: You must solve a system of equations.)
(x+2y)+(11x)=180
Show work

Answer 1

Is the 2nd equation this:

(x+2y)+(11x)=180

or this:
(x+2y)*(11x)=180

Answer 2

No it's plus sign between them
(x+2y)+(11x)=180

Answer 3

1st equation:
x+y=40
y=40-x

2nd equation:
x+2y+11x=180
12x+2y=180
6x+y=90

Substituting y with (40-x)
6x+40-x=90
5x=50
x=10

y=40-x=40-10=30

So x=10 , y=30

Answer 4

I understood everything except the last one
y=40-x=40-10=30
So x=10, y=30
can u explain the last part more

Answer 5

no never mind I got it
thank u so much that was very helpful
