4-\left(2x+5\right)=2\left(x+1\right)-16x+24
Multiply both sides of the equation by 8, the least common multiple of 2,8,4.
4-2x-5=2\left(x+1\right)-16x+24
To find the opposite of 2x+5, find the opposite of each term.
-1-2x=2\left(x+1\right)-16x+24
Subtract 5 from 4 to get -1.
-1-2x=2x+2-16x+24
Use the distributive property to multiply 2 by x+1.
-1-2x=-14x+2+24
Combine 2x and -16x to get -14x.
-1-2x=-14x+26
Add 2 and 24 to get 26.
-1-2x+14x=26
Add 14x to both sides.
-1+12x=26
Combine -2x and 14x to get 12x.
12x=26+1
Add 1 to both sides.
12x=27
Add 26 and 1 to get 27.
x=\frac{27}{12}
Divide both sides by 12.
x=\frac{9}{4}
Reduce the fraction \frac{27}{12} to lowest terms by extracting and canceling out 3.
