s=number of studne tickes bouthgt
a=number of adult tickets bought
300 tickest sold
total=300
a+s=300
value=rate times number of peple
student value=4s
adults value=10a
total value=1950
4s+10a=1950
a. system of equations are
s+a=300
4s+10a=1950
b. solve
s+a=300
4s+10a=1950
a+s=300
multiply by -4
-4s-4a=-1200
add to other eqaution
4s+10a=1950
<u>-4s-4a=-1200 + </u>
0s+6a=750
6a=750
divide 6
a=125
subsiute
s+a=300
s+125=300
subtract 125
s=175
a. s+a=300
4s+10a=1950
b. solution above
175 students
125 aduls
For this case we have the following equation:
Resolving we have:
We apply distributive property to the terms of parentheses:
Adding 6 to both sides of the equation:
Dividing between 3 on both sides of the equation:

1) <span>x + 24=95
2) 1 / 5x = 10
5x = 10/1
5x = 10
x = 10/5
x = 2
3) b/5 + 15 = 45
b = 5(45-15)
b = 150
