Question

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

Answer 1

Answer:

w = 10

Step-by-step 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.

• $↬ \sf \frac{4w}{4} = \frac{40}{4}$
• $↬ \sf w = 10$
