Question

Solve and then graph each solution on a number line.
52 = 12 + 4w

Answer 1

w = 10

Explanation:

• 52 = 12 + 4w

Move the constant to the left hand side and change their sign.

• 
  `\sf↬ 52 - 12 = 4w`

Subtract.

• 
  `↬ \sf \: 40 = 4w`

Divide both side by 4.

• 
  `↬ \sf (4w)/(4) = (40)/(4) \\`
• 
  `↬ \sf w = 10`
