Answer:

We know:

A+2B=777

2A+B=789

Let's rearrange the first equation to solve for A:

A=777-2B

Now let's plug 777-2B in for A in the second equation, and solve for B:

2(777-2B)+B=789

1554-4B+B=789

1554-789=3B

765=3B

B=255

Now we can substitute 255 in for B in the first rearranged equation, and solve for A:

A=777-2(255)

A=777-510

A=267

So candy bar A has 267 calories, and candy bar B has 255

I Hope it helps
