3x+4x+8x+16x+32x+64x=381
Combine x and 2x to get 3x.
7x+8x+16x+32x+64x=381
Combine 3x and 4x to get 7x.
15x+16x+32x+64x=381
Combine 7x and 8x to get 15x.
31x+32x+64x=381
Combine 15x and 16x to get 31x.
63x+64x=381
Combine 31x and 32x to get 63x.
127x=381
Combine 63x and 64x to get 127x.
x=\frac{381}{127}
Divide both sides by 127.
x=3
Divide 381 by 127 to get 3.
