Step-by-step explanation:
The question is not properly structured but we can as well find the sum of 5/7 and 10 as shown;

Hence the expression written in equivalent form of common denominator is 
The sum is 
 
        
             
        
        
        
5 because increased by means to add 2+3 
and quotient means the answer to a division problem 10/2 so ur answer is 5
        
             
        
        
        
Answer:
1. x=0
2. m=5
3. x=8
4. x=-8
5. x=49
6. x=-133
Step-by-step explanation:
1. 9x=0
2. -20=-4m, 20=4m
3. 2x=16
4. x/8=-1, x=-1x8
5. x/7=7
6. After simplifying: −1/19(x)=7
Hope this helped, I just simplified all the steps for the step by step explanation. Have a great day and stay safe, happy, and healthy!

Answer:
Number of children = 386
Number of adults = 287
Step-by-step explanation:
Let
x = number of children
y = number of adults
x + y = 673 (1)
1.75x + 2y = 1249.50 (2)
From (1)
x = 673 - y
Substitute x = 673 - y into (2)
1.75x + 2y = 1249.50
1.75(673 - y) + 2y = 1249.50
1177.75 - 1.75y + 2y = 1249.50
- 1.75y + 2y = 1249.50 - 1177.75
0.25y = 71.75
y = 71.75/0.25
y = 287
Substitute y = 287 into (1)
x + y = 673 
x + 287 = 673
x = 673 - 287
x = 386
Number of children = 386
Number of adults = 287
