4\left(x-5\right)=\left(x+2\right)\times 2-\left(4x+4\right)\times 3
Variable x cannot be equal to any of the values -2,-1 since division by zero is not defined. Multiply both sides of the equation by 4\left(x+1\right)\left(x+2\right), the least common multiple of x^{2}+3x+2,4x+4,x+2.
4x-20=\left(x+2\right)\times 2-\left(4x+4\right)\times 3
Use the distributive property to multiply 4 by x-5.
4x-20=2x+4-\left(4x+4\right)\times 3
Use the distributive property to multiply x+2 by 2.
4x-20=2x+4-\left(12x+12\right)
Use the distributive property to multiply 4x+4 by 3.
4x-20=2x+4-12x-12
To find the opposite of 12x+12, find the opposite of each term.
4x-20=-10x+4-12
Combine 2x and -12x to get -10x.
4x-20=-10x-8
Subtract 12 from 4 to get -8.
4x-20+10x=-8
Add 10x to both sides.
14x-20=-8
Combine 4x and 10x to get 14x.
14x=-8+20
Add 20 to both sides.
14x=12
Add -8 and 20 to get 12.
x=\frac{12}{14}
Divide both sides by 14.
x=\frac{6}{7}
Reduce the fraction \frac{12}{14} to lowest terms by extracting and canceling out 2.
