The answer you are looking for is -3.

To find this answer, you must get "n" by itself. First subtract 5 from both sides. You would get (-8)n = 24, which you then divide -8 on both sides, to get a final answer of n = -3.

I hope this helps!

Solve this system of equations by any method.<br> 5x + y = -13<br> 4x + 3y= -17

irga5000 [103]

5x + y = -13.....multiply by -3
4x + 3y = -17
-----------------
-15x - 3y = 39 (result of multiplying by -3)
4x + 3y = -17
-----------------add
-11x = 22
x = -22/11
x = -2

5x + y = -13
5(-2) + y = -13
-10 + y = -13
y = -13 + 10
y = -3

solution (-2,-3)

I need help with geometry

olchik [2.2K]

Answer:

m<1=?

m<2=4x-20..........(1)

m<4=3x-11.............(2)

Step-by-step explanation:

we have

m<2=m<4(corresponding angle of parrelelogram are equal)
4x-20=3x-11
4x-3x=20-11
x=9

again.we have

<1+<2=180(co-interior angle)

<1=180-<2=180-(4×9-20)=180-16=164
