Take the like terms on one side:
2m=6-14
2m = 8
m= 8/2
m= 4
Error: they divided both sides by three.
correct: they should’ve first subtracted both sides by two then divided both sides by three.
Answer:
Step-by-step explanation:
3w + 2c = 32
4w + 3c = 44
Multiply the 1st equation by 4 and 2nd equation by 3, we get:
12w + 8 c = 128
12w + 9 c = 132
Subtracting the top equation from the bottom equation, we get: c = 4
Substituting c = 4 in any one of the above equations and solving, we get: w = 8
Therefore, weight of 2w + 1c = 2(8) + 4 = 20 pounds (Answer)
100 - 80% = 20 %
20% = $416
416 x 5 = $2080 = 100%
