Welcome back! I cannot believe it is the start of a new year and a new semester. One thing that I am going to write about today is one thing I remember from the past semester is math. Well, I remember practically the entire lessons we worked on. I specifically remember one about distributive property and plugging in slopes to find an equation on a graph.
Since I remember a lot from last semester I am going to explain how to do a problem that pretty much sums everything we learned up. Here are the equations : y=1/2x-7 2y+4x=8
There are two ways to solve this, you can plug it in or make a balance equation.
The balance equation would be : 1/2x-7 = 2y+4x=8
However if you plug it in like this : 2(1/2x-7)+4x=8, that makes it a lot easier.
Now, to solve the problem, you can use either method. I am going to use the plug in method. First, you would distribute the 2 to 1/2x-7 and would end up with : x-14+4x=8. Then, you would combine like terms. Finish the problem from there and that explains what we learned in the past semester.
