Answer:

baguettes are b = $0.80

rolls are r = $0.30

Explanation:

1b + 4r = 2

3b + 2r = 3 step 1 when we need to balance and make one the same

6b + 4r = 6 step 2 when both equations must have 1 same value ie) 4r we take 2r and x2 to all values on that same equation.

6b + 4r = 6

-

1b + 4r = 2 step 3 when both equations show add we subtract them

5b = 4

b = 4/5

b = 0.8 b = 0.8 = 4/5 step 4 when we find x we plug in for x in this case we found b and plug in for b

1(0.8) + 4r = 2

0.8 + 4r = 2

4r = 2 - 0.8

4r = 1.2

r = 1.2 /4

r = 0.3
