False. To make it true, change the RHS to $5+2x.$

Work Step by Step

Two algebraic expressions are equivalent if they have the same value for ALL replacements. replace x with 0: LHS = $2(0)+5=5$ RHS= $5(0)+2=2$ so, the equality does not hold up, the two expressions are not equivalent. To make it true, change the RHS to $5+2x.$ $2x+5=5+2x$, because addition is commutative.
