let the number of adult tickets be x and the number of children tickets be y
3x + y = 164...equ(1)
2x + 3y = 174....equ(2)
multiplying equation 1 by 3
9x + 3y = 492
subtracting equation 2 from 1
7x = 318
x = 45.43 dollars
substituting the value of x into the equation
3(45.428) + y = 164
y = 164 - 3(45.428)
∴y = 27.71 dollars
2x+6 - х -4
2x - x = - 4 - 6
x=-10
20x - 8 = 18x +6
20x - 18x = 6 +8
2x = 14
x=7
Step-by-step explanation:
Hello there!
Just double the given sides!
