2\left(a-4\right)=7\left(a+11\right)
Multiply both sides of the equation by 14, the least common multiple of 7,2.
2a-8=7\left(a+11\right)
Use the distributive property to multiply 2 by a-4.
2a-8=7a+77
Use the distributive property to multiply 7 by a+11.
2a-8-7a=77
Subtract 7a from both sides.
-5a-8=77
Combine 2a and -7a to get -5a.
-5a=77+8
Add 8 to both sides.
-5a=85
Add 77 and 8 to get 85.
a=\frac{85}{-5}
Divide both sides by -5.
a=-17
Divide 85 by -5 to get -17.
