16x-15=20\left(2\times 2+1\right)
Multiply both sides of the equation by 40, the least common multiple of 5,8,2.
16x-15=20\left(4+1\right)
Multiply 2 and 2 to get 4.
16x-15=20\times 5
Add 4 and 1 to get 5.
16x-15=100
Multiply 20 and 5 to get 100.
16x=100+15
Add 15 to both sides.
16x=115
Add 100 and 15 to get 115.
x=\frac{115}{16}
Divide both sides by 16.
