51\left(x-5\right)+51\left(x-4\right)+50\left(x-3\right)=1020\left(x-100\right)+1275\left(x-101\right)+1700\left(x-102\right)
Multiply both sides of the equation by 5100, the least common multiple of 100,102,5,4,3.
51x-255+51\left(x-4\right)+50\left(x-3\right)=1020\left(x-100\right)+1275\left(x-101\right)+1700\left(x-102\right)
Use the distributive property to multiply 51 by x-5.
51x-255+51x-204+50\left(x-3\right)=1020\left(x-100\right)+1275\left(x-101\right)+1700\left(x-102\right)
Use the distributive property to multiply 51 by x-4.
102x-255-204+50\left(x-3\right)=1020\left(x-100\right)+1275\left(x-101\right)+1700\left(x-102\right)
Combine 51x and 51x to get 102x.
102x-459+50\left(x-3\right)=1020\left(x-100\right)+1275\left(x-101\right)+1700\left(x-102\right)
Subtract 204 from -255 to get -459.
102x-459+50x-150=1020\left(x-100\right)+1275\left(x-101\right)+1700\left(x-102\right)
Use the distributive property to multiply 50 by x-3.
152x-459-150=1020\left(x-100\right)+1275\left(x-101\right)+1700\left(x-102\right)
