8x-5y=15 <br>6x+4y=43<br>solve the system by any method​
Sedbober [7]

Answer:

x=\frac{275}{62} , y=\frac{127}{31}

Step-by-step explanation:

<h3>I will use the elimination method.</h3>

We want to make the X's the same:

24x-15y=45

24x+16y=172

Because the signs of the X's are the same we subtract the 2 equations to make:

(I put the second one on top of the 1st)

31y=127

So:

y=\frac{127}{31}

Substitute y into either equation 1 or 2:

(I chose equation 1)

8x-5(\frac{127}{31})=15

8x=5(\frac{127}{31}) + 15

x=\frac{5(\frac{127}{31})}{8}

So:

x=\frac{275}{62}
