The difference of 3 times a number and 4 is -19. what is the answer?

-3(-5)--> -3×(-5) equals -15 minus a positive 4 is -19

Step-by-step explanation:

subtract 4 from 19 and find out what factors can multiply together to get the difference from 19-4. In this case, it's 15. -3(-5) equal -15 and I'm subtracting a positive (4), which won't go down and equal 11 like we usually do it. when subtracting a positive from a negative. we go up. 19-4=15. -3x-5 equal -15-4=-19. Hope you get this!!
