Answer:
x = 12
Step-by-step explanation:
Hello!
The sum of 3x - 16 and 1 gives us 2x - 3.
<h3>
Solve for x</h3>
- 3x - 16 + 1 = 2x - 3
- 3x - 15 = 2x - 3
- x - 15 = -3
- x = 12
The value of x is 12.
The answer would be 0 if I'm correct.

<u>Corrected Question</u>
I am donating packages for Christmas drive. After the first week, I spent 126 to donate three children packages and 8 adult packages. After two weeks I spent 108 to donate six children packages and 4 adult packages. What is the price of each type of package
Answer:
Adult package costs $12
Child's package costs $10.
Step-by-step explanation:
Let the cost of a child's package =c
Let the cost of an adult package =a
<u>First Purchase</u>
Cost of three children packages and 8 adult package=$126
<u>Second purchase</u>
Cost of six children packages and 4 adult packages=$108
6c+4a=108
Multiply this equation by 2 to make the coefficient of a the same as the other equation
We solve the two resulting equations simultaneously
Subtract
-9c=-90
Divide both sides by -9
c=10
Substitute c=10 into 3c+8a=126 to solve for a
3(10)+8a=126
8a=126-30
8a=96
Divide both sides by 8
a=12
Therefore, an adult package costs $12 while a child's package costs $10.
