Let A represent amount of Type A coffee pounds used.

Let B represent amount of Type B coffee pounds used

A + B = 156

B = 156 - A

A = 156 - B

5.80A + 4.65B = 826.60

580 (156 - B) + 4.65B - 826.60 = 0

904.8 - 5.80B + 4.65B - 826.60 = 0

904.8 - 1.15B - 826.60 = 0

78.2 - 1.15B = 0

78.2/1.15 = 1.15B/1.15

68 = B

B = 68 pounds of Type B coffee

There's many more steps you can take to check and etc but am too lazy to put down sorry.
