Hi Joyce,
Try to understand what the english says
7 times a number: 7 number
is decreased by 8:  8
the result is the same as: =
3 times the number: 3 number
is increased by 6: + 6
Putting this all together I get
7 number  8 = 3 number + 6
I used the word number to stand for the unknown quantity, usually we use one letter like x so the equation is
7 x  8 = 3 x + 6
Can you solve for x now?
