False; $(5+3)(x-4)=8(x-4)=8x-32$

Work Step by Step

First, check if there are two identities for the equations. Then simplify the expression. $5+3(x-4)=8(x-4)=8x-32$ $5+3(x-4)=5+3x-12=3x-7$ $8(x-4)=8x-32$ $8x-32=8x-32$ Notice that the last two expressions are identical while the first is different. This makes the statement false.
