216x-72-3\left(4x+5\right)\leq x-4\left(x-7\right)
Use the distributive property to multiply 72 by 3x-1.
216x-72-12x-15\leq x-4\left(x-7\right)
Use the distributive property to multiply -3 by 4x+5.
204x-72-15\leq x-4\left(x-7\right)
Combine 216x and -12x to get 204x.
204x-87\leq x-4\left(x-7\right)
Subtract 15 from -72 to get -87.
204x-87\leq x-4x+28
Use the distributive property to multiply -4 by x-7.
204x-87\leq -3x+28
Combine x and -4x to get -3x.
204x-87+3x\leq 28
Add 3x to both sides.
207x-87\leq 28
Combine 204x and 3x to get 207x.
207x\leq 28+87
Add 87 to both sides.
207x\leq 115
Add 28 and 87 to get 115.
x\leq \frac{115}{207}
Divide both sides by 207. Since 207 is positive, the inequality direction remains the same.
x\leq \frac{5}{9}
Reduce the fraction \frac{115}{207} to lowest terms by extracting and canceling out 23.
