-x+4y= -17
-x= -17-4y multiply everything by -1
x=17+4y

-6X-2y=2
-6(17+4y) - 2y=2
-102-24y-2y=2
-26y=2+102
-26y=104
y= -104/26
y= -4

x=17+4y
x=17+4•4
x=17+16
x=33

What is the result of adding these two equation?<br> 5x-9y=1<br> -7x+2y=-5
SCORPION-xisa [38]

The result of adding the given equations is 2x+7y=4.

Step-by-step explanation:

Given equations are;

5x-9y=1     Eqn 1

-7x+2y=-5   Eqn 2

Adding Eqn 1 and 2

(5x-9y)+(-7x+2y)=1+(-5)\\5x-9y-7x+2y=1-5

Arranging alike terms;

5x-7x-9y+2y=-4\\-2x-7y=-4

Dividing each term by -1

\frac{-2x}{-1}+\frac{-7y}{-1}=\frac{-4}{-1}\\2x+7y=4

The result of adding the given equations is 2x+7y=4.

Keywords: addition, linear equations
