2\times 5+15=5\left(1\times 4+1\right)
Multiply both sides of the equation by 20, the least common multiple of 10,4.
10+15=5\left(1\times 4+1\right)
Multiply 2 and 5 to get 10.
25=5\left(1\times 4+1\right)
Add 10 and 15 to get 25.
25=5\left(4+1\right)
Multiply 1 and 4 to get 4.
25=5\times 5
Add 4 and 1 to get 5.
25=25
Multiply 5 and 5 to get 25.
\text{true}
Compare 25 and 25.
