Questions & Step-by-Step Solutions

Solve for y: 3y + 4 = 19.
Correct Answer: 5
  • Step 1: Start with the equation 3y + 4 = 19.
  • Step 2: To isolate the term with y, subtract 4 from both sides of the equation. This gives you 3y = 19 - 4.
  • Step 3: Calculate 19 - 4, which equals 15. Now the equation is 3y = 15.
  • Step 4: To solve for y, divide both sides of the equation by 3. This gives you y = 15 / 3.
  • Step 5: Calculate 15 divided by 3, which equals 5. So, y = 5.
  • Linear Equations – The question tests the ability to solve a basic linear equation by isolating the variable.
  • Operations with Equations – It assesses understanding of performing arithmetic operations (addition, subtraction, division) to manipulate equations.
