To solve this equation, we will first simplify both sides of the equation:
1/2(10s + 14d) = 1/2(10 * 5 + 14 * 4)
Distributing the 1/2 on both sides:
5s + 7d = 5 * 5 + 7 * 4
Now, multiply and simplify further:
5s + 7d = 25 + 28
5s + 7d = 53
Therefore, the solution to the equation is:
5s + 7d = 53
1/2(10s+14d)=1/2(10x5+14x4)
