The number of children's tickets bought was 300 and the number of adult tickets bought was 700
Step-by-step explanation:
Let
x ----> the number of children's tickets bought
y ----> the number of adult tickets bought
we know that

-----> equation A
-----> equation B
Solve the system by substitution
substitute equation A in equation B

solve for x




<em>Find the value of x</em>
therefore

10 more than twice a number: add 10 to 2x
Answer: 2x+10
