If the cost of adult ticket is x and that of children ticket is y
Then 3x +y = $38
         3x+2y =$52, solving simultaneously
we subtract the two equation,
              -y = -14 
thus; y =14 
to get x we substitute y with 14
            3x = 38-14
              3x =24
                x =8
Therefore, the cost of 1 adult ticket is $8 while the cost of children ticket is $14

Solve the system:<br> 4x – 3y = -21<br> X=-y-14
Liula [17]

Answer:

The solution for the system of equations is

x=2,y=−2

Explanation:

4x−3y=14.....equation (1)

y=−3x+4.....equation (2)

Solving by substitution

Substituting equation 2 in equation 1

4x−3⋅(−3x+4)=14

4x+9x−12=14

13x=14+12

13x=26

x=2

Finding y by substituting x in equation 1

4x−3y=14

4⋅2−3y=14

8−3y=14

8−14=3y

3y=−6

y=−2
