One way is subsitute
I like solving

so

what you do is this
add the equaitons to gether to eliminate x

2y=x+5
<u>3y=-x-3 +</u>
5y=0x+2
5y=2
y=2/5

sub back


2y=x+5
2(2/5)=x+5
4/5=x+5
minus 5
4/5-25/5=x
-21/5=x

the point is (x,y) or
(-21/5,2/5)
aprox
(-4.2,0.4)

the closes one is
hmm, x=-3
and y=1

A middle school took all of its 6th grade students on a field trip to see a ballet. The
Advocard [28]

By working with percentages, we will see that there are 1,080 seats in the theater.

<h3>How many total seats were in the theater?</h3>

We know that the students filled 702 seats, leaving 35% vacant.

Then 702 seats represents the (100% - 35% = 65%) of the total number of seats.

So, if the total number of seats is S, we can write:

(65%/100%)*S as the 65% of S.

Then we solve:

(65%/100%)*S = 702

0.65*S = 702

S = 702/0.65 = 1,080

There are 1,080 seats in the theater.
