Answer and Step-By-Step Explanation:

How to solve the problem?

[tex]4 \: + \: 3x = 25?[/tex]

Step 1: Solve:

Rearrange the problem:

[tex]4 + 3x = 25.\\3x + 4 = 25.[/tex]

Step 2: Subtract 4 from both sides of the equations:

[tex]3x \: + \: 4 = 25\\3x \: + \: 4 - 4 = 25 - 4[/tex]

Step 3: Simplify:

  • Subtract the numbers:
  • [tex]3x \: + \: 4-4 = 25 - 4[/tex]
  • Subtract the numbers (again):
  • [tex]3x = 25-4\\3x = 21[/tex]
  • The Answer:
  • [tex]3x=21[/tex]

Step 4: Divide both sides of the equation by the same term:

[tex]3x = 21\\\\\frac{3x}{3} = \frac{21}{3}[/tex]

Step 5: Cancel the terms that are in both the numerator and denominator:

[tex]\frac{3x}{3} = \frac{21}{3}\\\\x = \frac{21}{3}[/tex]

Divide the numbers:

[tex]x = \frac{21}{3}\\\\x = 7[/tex]

FINAL ANSWER:

[tex]x = 7[/tex]
