Answer:
<h2>
John has $15 and Alex has $33</h2>
Step-by-step explanation:
a systems of equations can be made from the information on the problem
x+y=48
x=2y+3
since x= 2y+3 substitute 2y+3 in the firat equation to get:
(2y+3)+y=48 -> 3y+3=48 -> 3y=45 -> y=15
plug in 15 for y in the second equation to solve for x
x+15 =48 --> x=33
third option is the correct answer....
Answer:
.
Step-by-step explanation:
Isolate the variable, and see what kind of equation it is. if it's adding, let's say, then add one number to itself. this cancels it out, so it's taken care of. next, add that same number to the second one, and take the result. you should be able to subtract that from the answer i believe, it's been a while since I've done these so it might not be spot on
