The input number is supposed to be substituted for x in the (3x + 5)
so the first one would be (3(0) + 5) = 5
15 ft = 180 inches
180/18 = 10
Therefore, each part is 10 inches long.
Subtracting a negative means that you will add the number. Convert the symbols to get the following:
y + 10 = 12
Subtract 10 from both sides.
y = 2
Answer:
For the top equation, x = 27 (I think you meant to put x - 27 = 0. If not, I can always edit my answer for you)
For the bottom, x = 3
Hope this helps! Have a grrrreat day lol
