Add the two rows together
3x = 12
Solve for x in the above equation
x = 4
Substitute x = 4 into any of the two equations above. Let's choose the first one; 2x - y = 6
2 × 4 - y = 6
Solve for y in the above equation
y = 2
Thus,
<u>x = 4</u>
<u>y = 2</u>
We know that there are two tickets (which we'll represent with x) and a fee for transporation (which is $20)
So we can set up the equation 20+2x=48
We want to isolate x so we'll subtract 20 from each side, which gives us the equation
2x=28
Then divide each side by 2
Giving us the final answer of
x=14
So each ticket costs $14

Step-by-step explanation:
The new ratio of the number of cookies in Jar A to the number of cookies in Jar B in the end is 5 : 19
<h3>How to find ratio</h3>
Ratio of jar A to jar B = 3 : 8
Jar B = 1/2 of A + B
= 1/2 × 3 + 8
= 3/2 + 8
= (3+16) /2
= 19/2
Jar A = 3 - 1/2
= (6-1) /2
= 5/2
New ratio of jar A to jar B = 5/2 : 19/2
= 5/2 ÷ 19/2
= 5/2 × 2/19
= 5/19
= 5 : 19
