Questions & Step-by-Step Solutions

If x = 4, what is the value of 3x - 2? (2019)
  • Step 1: Identify the value of x. Here, x = 4.
  • Step 2: Substitute the value of x into the expression 3x - 2. This means we replace x with 4.
  • Step 3: Calculate 3 times 4. This gives us 3(4) = 12.
  • Step 4: Now, subtract 2 from 12. So, we calculate 12 - 2.
  • Step 5: The result of 12 - 2 is 10.
  • Algebraic Expression Evaluation – The question tests the ability to evaluate a linear expression by substituting a given value for the variable.
