You would solve a problem like this:

3(2x-5)=21

6x-15=21... I multiplied 2x and -5 by 3

6x-15=21

6x-15+15=21+15... I added 15 to both sides so 6x can be alone

6x=36

6x/6=36/6... I divided by 6 from both sides to leave x alone to get the answer:

x=6.

sdas [7]

Answer:    30 $15 tickets and 20 $35 tickets

Step-by-step explanation:

.X%2BY=50

2.15X%2B35Y=1150

From eq. 1,

15X%2B15Y=750

Subtract from eq. 2,

15X%2B35Y-15X-15Y=1150-750

20Y=400

Y=20

Then,

X%2B20=50

X=30

30 $15 tickets and 20 $35 ticket

Hope it helps
