Answer:
l = 9/2 or 4.5
m = 11/4 or 2.75
Step-by-step explanation:
4l + 8m = 40
8m = 40 - 4I
m = 5 - 0.5l
5l + 2m = 28
5l + 2(5 - 0.5l) = 28
5l + (10 - l) = 28
4l + 10 = 28
4l = 18
l = 18/4 or 9/2
l = 4.5
4l + 8m = 40
4(4.5) + 8m = 40
18 + 8m = 40
8m + 18 = 40
8m = 22
m = 22/8
m = 2.75
The LCD of the number part is 3 and since there is a variable in one term you have to use it in the LCD.
