The problem is in the snippet below only correct answers hmu if you are good at these and i will just have you answer more questions so i can just pay you like 100? ?

a = 6   b=  7

Step-by-step explanation:

4 (b-1) = 3b + 3       substitue for a

4b - 4 = 3b + 3       subtract 4b from both sides

-4 = 3b + 3 - 4b       =        -4 = -b + 3        combine 3b and (-4b)

-7 = -b      divide by -1 for both sides

7 = b

4a = 3 × 7 + 3       substitute for b

4a = 24             combine like terms

a = 6       divide by 4 on both sides

a = 7 -1

a = 6

78.59 is the mean
