To isolate -1 we need to subtract 2m from both sides
2m - 1 = 3m (SUBTRACT 2m)
To isolate 1 we need to subtract m from both sides
2m = 1 + m (SUBTRACT m)
To isolate m we need to add 1 from both sides
m - 1 = 2 (ADD 1)
To isolate m we need to subtract 2 from both sides
2 + m = 3 (SUBTRACT 2)
To isolate m we need to add 2 from both sides
-2 + m = 1 (ADD 2)
To isolate m we need to subtract 1 from both sides
3 = 1 + m (SUBTRACT 1)

Step-by-step explanation:
Answer:
3,5,7,9,11
Step-by-step explanation:
You would put the whole numbers in order as n and solve
1. 1*2+1 = 3
2. 2*2+1 = 5
3. 3*2+1 = 7
4. 4*2+1 = 9
5. 5*2+1 = 11
You would notice that the numbers are odd numbers in order
Step-by-step explanation:
Let the number of children that swam be A
Let the number of adults that swam be B
1.75A+2B=1113.75 Equation 1
Total number of people that used that pool =602
A+B=602 Equation 2
These are simultaneous Equations
multiply Equation 2 by(2) on both the sides we get
2A+2B=1204 Equation 3
Subtract Equation 1 from Equation 3
2A+2B=1204 Equation 3
1.75A+2b=1113.75 Equation 1
<u> - - -</u>
.25A+0 =90.25
.25A=90.25
A=90.25/.25
A=361
putting value of A in Equation 2 we get
361+B=602
B=602-361
B=241
so number of children is 361
and number of adults is 241
