Solve by addition method <br>3x+y=8 <br>2x-y=7
Vinil7 [7]

Answer:

(3,-1)

Step-by-step explanation:

So we have the system of equations:

3x+y=8\\2x-y=7

As directed, add straight down. The y-variable will cancel:

5x=15

Now, divide both sides by 5. The left cancels:

x=3

So x is 3.

Now, substitute 3 for x in either of the equations:

3x+y=8

Substitute 3 for x:

3(3)+y=8

Multiply:

9+y=8

Subtract 9 from both sides:

y=-1

So, our answer is: x=3, y=-1 or (3,-1).

And we are done :)
