X=area of Sahara. y=area of the Gobi Desert. We suggest this system equations: x+y=4000000 x=7y solve by susbstitution method. (7y)+y=4,000,000 8y=4,000,000 y=4,000,000 / 8=500,000
x=7y x=7(500,000)=3,500,000
The area of Sahara=3,500,00 miles². The area of the Gobi Desert=500,000 miles²
To check: Te sum of their areas is : 3,500,000 miles²+500,000 miles²=4,000,000 miles² Te area of sahara (3,500,000 miles²) is 7 times the area of the Gobi Desert (7*500,000 miles²=3,500,000 miles²).
first you sympypfly the answer and then what you want to do is mutyplying te answer by the formula of the graph by then you should already have the table of the formula,then what you want to do is to try to coordinate the number of the graph,AND THA'S HOW YOU GET (-6,1)
