Simple Examples: How to Solve β€œSet Equal to 7”

Let’s consider common forms such as:

1. Solve for x:
  x + 3 = 7
  Subtract 3 from both sides:
  x = 7 – 3 β†’ x = 4

2. Solve for x:
  2x = 7
  Divide both sides by 2:
  x = 7 Γ· 2 β†’ x = 3.5

3. Word Problem:
_A quick runner trains to run a lap in a time that equals 7 seconds. How long do they run?
  Set equal: t = 7 β†’ t = 7 seconds.
