The basic unit of length in the metric system is the meter. Grams are
used to measure weight and liter is used to measure liquid capacity
besides, it is used so that you can express very large and very small numbers in a short
unambiguous manner.
Example Instead of saying "three thousand
million" meters
They classify the decimal place of the basic unit. ie, the meter is
classified with milli (1/1000), centi(1/100), deci (1/10), Deca (10),
Hecto (100), Kilo (1000).
35 + 52 + 3(x + 2) = 180
87 + 3x + 6 = 180 ( add the like terms and use distributive property)
93 + 3x = 180
-93 -93
3x = 87
÷3 ÷3
x = 29
( the sum of all triangle angles is 180)

Hello! Remember to write complete questions in order to get good and exact answers. Here you don't provide any system so I couldn't help you in an exact way, but in a general manner. When solving systems by graphing we just need to find the points of intersection of the graphs of the functions that built up the system.
Suppose you have the following system of linear equation:

yBy using graphing tools, we get the graph shown below. As you can see, the point of intersection of both lines is
