Answer:
- We want to remove the 2 first. Since the original equation is + 2 , we're gonna use the opposite operation and subtract 2 form both sides.
- Simplify! 2 - 2 = 0 on the left and 26 - 2 = 24 on the right.
- Then we need to think about how to remove the coefficient 12 . Since the opposite of multiplication is division , we're going to divide both sides by 12.
- Simplify. 12/ 12 = 1 on the left and 24 / 12 = 2 on the right. So our answer is x = 2 .

<h3><em><u>SOLUTION:</u></em></h3>The image of the question is attached below.
Given each unit length = 1 foot
Tile cost per square feet = $1. 65
To find the area, split the floor shape into two shape.
One is trapezoid and the other is parallelogram.
Let's count the grid given.
The parallels sides of trapezoid are 7 ft and 4 ft, height is 7 ft.
The base and height of the parallelogram are 4 ft and 4 ft respectively.
Area of the trapezoid =1/2 ×(sum or parallel sides)× height
=1/2× (7+4)×5
=1/2×11×5
Area of the trapezoid = 27.5 sq.ft
Area of the parallelogram = base × height
= 4 ft × 4 ft
Area of the parallelogram = 16 sq. ft
Total area = 27.5 sq. ft + 16 sq. ft
= 43.5 sq. ft
Cost of area per sq. ft = $1.65
Cost of area 43.5 sq. ft = 43. 5 × 1.65
= $71.775
= $71.78
Hence Sal will pay $71.78 to tile his entryway.
