3(x + 4) = 3x + 4
3x + 12 = 3x + 4
3x - 3x = 4 - 12
0 = -8 (incorrect....no solution)

little tip ...
if it ends with a variable equaling a number, like x = 2 or y = 4, then there is 1 solution.
if it ends with something unequal with no variable, like 0 = -4 or 5 = 7, then there is no solution.
if it ends with something equaling with no variable, like 2 = 2 or 5 = 5, then there is infinite solutions.

Linda left home and drove for 2 hours. She stopped for lunch then drove for another 3 hours at a rate that is 10 mph higher than
Verdich [7]

Answer:

44 mph

Step-by-step explanation:

Given that:

Before lunch :

Time taken = 2hrs ; at speed = x mph

After lunch :

Time taken = 3hrs ; at speed = x + 10 mph

Total distance covered = 250 miles :

Distance = speed * time

(2 * x) + (3 * (x + 10)) = 250

2x + 3x + 30 = 250

5x + 30 = 250

5x = 250 - 30

5x = 220

x = 220/ 5

x = 44 mph

Rate before lunch is 44mph
