2(x-5) +3x = 4x - 2

2x - 10 + 3x = 4x - 2

Simplify
5x - 10 = 4x - 2

Subtract 4x  to both sides
5x - 10 -4x  = 4x - 2 -4x 

Simplify
x - 10 = -2
add 10 to both sides
x - 10 +10 = -2 +10
Simplify

First start with the parenthesis so 
2x-10+3x=4x-2
add like terms together
5x-10=4x-2
next send the x and numbers to their own sides
x=8

Given is :

The area of the rectangular patio is = 130 square feet

Let the width of the patio be = x feet

As length is 3 feet more than the width, so the length is = x+3 feet

Now area of rectangle is = length * width

x(x+3)=130

x^{2}+3x=130

x^{2}+3x-130=0

x^{2}+13x-10x-130=0

x(x+13)-10(x+13)=0

(x-10)(x+13)=0

This gives either x-10=0 or x+13=0

x-10=0 ; x=10

x+13=0 ; x=-13 (neglect this negative value)

So, the width of the patio is = 10 feet

Length = 10+3 = 13 feet
