<span>For the first one:
Simplifying ax + by = 12
Solving ax + by = 12
Solving for variable 'a'.
Move all terms containing a to the left, all other terms to the right.
Add '-1by' to each side of the equation. ax + by + -1by = 12 + -1by
Combine like terms: by + -1by = 0 ax + 0 = 12 + -1by ax = 12 + -1by
Divide each side by 'x'. a = 12x-1 + -1bx-1y
Simplifying a = 12x-1 + -1bx-1y
Reorder the terms: a = -1bx-1y + 12x<span>-1

For the second one:
</span></span><span>Simplifying 2x + 8y = 60
Solving 2x + 8y = 60
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-8y' to each side of the equation. 2x + 8y + -8y = 60 + -8y
Combine like terms: 8y + -8y = 0 2x + 0 = 60 + -8y 2x = 60 + -8y
Divide each side by '2'. x = 30 + -4y
Simplifying x = 30 + -4y

<h3>Division problem</h3>

Width of patio = 5 2/3 feet

Area of patio = 36 5/6 sq. feet

Length will be: area /width

36 5/6 divides by 5 2/3

221/6 divides by 17/3

221/6 * 3/17

13/2

6 1/2 feet

Length is 6 1/2 feet, that means we can place the concrete patio on a 7 foot picnic table.

17) Area of mirror = 225 sq. inches

Width of mirror = 13 3/4 inches.

Length of mirror will be=area/ width

225 divides by 13 3/4

225 divides by 55/4

225 * 4/55

180/11

16 4/11

The width of mirror will be 16 4/11 feet. It is greater than 16 feet. Therefore mirror can't be fit in a space of 15 inches by 16 inches.

18) Total length of fabric = 16 1/5 yards

One fabric piece size= 5 2/5

Number of fabric pieces will be= total length/ 1 fabric length

16 1/5 divides by 5 2/5

81/5 divides by 27/5

81/5*5/27

3

There will be total 3 pieces of size 5 2/5 yards.
