Solving multi-step problems using linear equations in one variable

Gracie wants to increase the size of her garden.  If A = lw represents the current area of her garden, what is an equation that can be used to represent the resulting are of Gracie's garden if she increases the length by 5 and doubles the width?

• A = 10lw
• A = 2wl + 10w
• A = 2w (l - 5)
• A = 10wl + 2w

Solve the following equation:

 $-3=12y-5\left(2y-7\right)$
