Answer:
The line would be straight; it could be vertical or horizontal.
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).
Y=8x-23
y eqauls eight x minus twenty three
It’s D
2y-x=6
2(3)-x=6
6-x=6
-x=6-6
-x=0
Divided by- it will not gonna change
2y-x=6
2y-(-2)=6
2y+2=6
2y=6-2
2y/2=4/2
Y=2
