Answer:
Let's solve for x.
4x+5y=7
Step 1: Add -5y to both sides.
4x+5y+−5y=7+−5y
4x=−5y+7
Step 2: Divide both sides by 4.
4x/4=−5y+7/4
x=−5/4 y+ 7/4
Answer: for the first one x=−5/4 y+ 7/4
3x−2y=−12
Step 1: Add 2y to both sides.
3x−2y+2y=−12+2y
3x=2y−12
Step 2: Divide both sides by 3.
3x/3=2y−12/3
x=2/3y−4
Answer:
x=2/3y−4

The actual distance between Yappy city and Quiet city when it is 23 cm in map is 9.2 miles.
What is scaling ?
It is the technique to resize drawing with comparing to actual size of object which uses proportion or ratio. For example, Mapping of earth, drawing prototype of automobiles.
It is given that :
The distance on the map between Yappy city and Quiet city is 23 cm
and,
5cm = 2 miles
now, for 1 cm on map it is equal to 2/5 miles of actual distance.
Therefore to find the actual distance of 23 cm in map we simply multiply 23 with 2/5 :
actual distance :
2/5 x 23 = 9.2 miles
Therefore, the actual distance between Yappy city and Quiet city is 9.2 miles.

Answer:
36
Step-by-step explanation:
Let number of m&ms Garry has be g
number of m&ms Larry has be l
Number of m&ms Jerry has be j
Since Gary has TWICE as Larry, we can write:
g = 2l
Also, Jerry has THRICE as Larry, we can write:
j = 3l
Together, they have 108, thus, we can write:
g + l + j = 108
Putting 1st and 2nd equation in 3rd, we can solve for Larry first. Shown below:
Larry has 18. To find Gary's number, we can use the fact g = 2l, so
g = 2 * 18 = 36
Gary has 36 m&ms
