I just need a step by step expiation please!

first I would combine terms which would give me

-4x-7=-7-4x

then I would get the variable on each side of the equal sign

0=0

lastly I would verify the solution

infinite solutions

Step-by-step explanation:

combining combining like terms would give you negative 4x - 7 which is equal to -7 - 4x. if you were to add 7 on either side and 4 on either side you would get 0 = 0 because this is correct it's infinite solutions

hey i’m new i won’t be answering any questions now bye peeps see you next time

the figures below are made out of circles, semicircles, quarter … find the area and the perimeter of each figure and give your answers as a completely simplified exact value in terms of π (no approximations). remember that we'll also have to cut whatever areas we get in half, since we're only dealing im pretty sure that is the right answer
