12x-4-5\left(x+2\right)=7\left(2x+5\right)-\left(3x-16\right)
Use the distributive property to multiply 4 by 3x-1.
12x-4-5x-10=7\left(2x+5\right)-\left(3x-16\right)
Use the distributive property to multiply -5 by x+2.
7x-4-10=7\left(2x+5\right)-\left(3x-16\right)
Combine 12x and -5x to get 7x.
7x-14=7\left(2x+5\right)-\left(3x-16\right)
Subtract 10 from -4 to get -14.
7x-14=14x+35-\left(3x-16\right)
Use the distributive property to multiply 7 by 2x+5.
7x-14=14x+35-3x-\left(-16\right)
To find the opposite of 3x-16, find the opposite of each term.
7x-14=14x+35-3x+16
The opposite of -16 is 16.
7x-14=11x+35+16
Combine 14x and -3x to get 11x.
7x-14=11x+51
Add 35 and 16 to get 51.
7x-14-11x=51
Subtract 11x from both sides.
-4x-14=51
Combine 7x and -11x to get -4x.
-4x=51+14
Add 14 to both sides.
-4x=65
Add 51 and 14 to get 65.
x=\frac{65}{-4}
Divide both sides by -4.
x=-\frac{65}{4}
Fraction \frac{65}{-4} can be rewritten as -\frac{65}{4} by extracting the negative sign.
