No this number is not written in scientific notation
In scientific notation, it'll look like
4.8 * 10 ^14
In scientific notation it's 10 ^ n
NOT 100^n
Hope this helps
-4(-x-10)= 4x• 40
11g+4-6g+7s-10 =16g+6-7s
3(10+9x)+11-3x= 13x+19
Is there supposed to be a attached file? Or are you confused about the topic in general. I can help if need be. I’ll start off with saying that a system of equation is two equations that either have infinite, no, or one solution. This solution makes x true for both equations. x will be the same value for each equation.
