What exactly is simplification?
Simplifying means making something easier to do or comprehend, as well as making something less difficult.
From the table the following data is observed ;
The total no of 7th-grade students is 128
The no of 7th-grade students who comes by bus is 79
The total no of 7th-grade students who comes to school either by bus or by bike as;
Student by bus + Student by bike = Total no of a seventh-grade student
Let the no of seventh-grade student comes to school by bike is x, and the following equation is obtained;
Student by bus + Student by bike = Total no of seventh grade student
x+79=128
x=128-79
x= 49
The total no of 7th-grade students who come to school by bike will be 49.
