If 19 is subtracted from three times a number, the difference is 110. What is the number? *

Step-by-step explanation:

Three of you is 3 Sarahs. 3 times a number is 3n, or 3-whatever letter you pick. Subtract 19 from that...

3n - 19

If it confuses you, pick an actual number to use. 19 subtracted from 3 times 6.

3(6) - 19

Instead of solving and getting 1, just replace the 6 with a letter. Most people like to use x, but I used n since "number" starts with n.

3n - 19

the answer is d

step-by-step explanation:

y+3=-4(x-2)

y+3=-4x+8
