Answer:

42 boys

Step-by-step explanation:

Represent the number of boys with 'b' and that of girls with 'b + 23.'

Then b + (b + 23) = 207.

Simplifying, we get 2b = 84, so that b is 42. There are 42 boys and

(42 + 23) girls, or 65 girls.

Two numbers total 86 and have a difference of 12. Find the two numbers.

mestny [16]

Let the two numbers be x and y.

x + y = 86
+
x - y = 12
_________
2x + 0 = 98
__________

2x = 98

x = 98/2

x = 49

From x + y = 86

49 + y = 86

y = 86 - 49

y = 37

The numbers are 49 and 37.
