Question

2. solve the equation r/2-6=14

3. solve the equation 12+4m=24

Answer 1

2. To solve the equation r/2-6=14, you need to isolate r on one side of the equation by adding 6 to both sides, then multiplying both sides by 2. The steps are:

r/2-6=14
+6 +6 (add 6 to both sides)
r/2 = 20
x2 x2 (multiply both sides by 2)
r = 40

Therefore, r equals 40.

3. To solve the equation 12+4m=24, you need to isolate m on one side of the equation by subtracting 12 from both sides, then dividing both sides by 4. The steps are:

12+4m=24
-12 -12 (subtract 12 from both sides)
4m = 12
/4 /4 (divide both sides by 4)
m = 3

Therefore, m equals 3.
