To simplify the expression (3+2y)×8-10, we can use the distributive property of multiplication over addition/subtraction, which states that a(b + c) = ab + ac and a(b - c) = ab - ac. Using this property, we can simplify the expression as follows:
(3+2y)×8-10 = 24 + 16y - 10
= 14 + 16y
Therefore, the equivalent expression of (3+2y)×8-10 is 14 + 16y.
