Six times the sum of a number and 9 equals 3

6(x + 9) = 3. x = -7

Step-by-step explanation:

if you distribute first it gives you 6x + 45 = 3 then you subtract 45 from each side which gets you 6x=-42 then divide by 6 to get x = -7.

= 5

step-by-step explanation:

to find the 15th term substitute n = 15 into the nth term formula

= (- 3 × 15 ) + 50 = - 45 + 50 = 5
