Work Step by Step

We are given that $5+7(x+1)=12+10x$. In order to solve for x, we must first simplify the left side using the distributive property. $5+7x+7=12+10x$ Group like terms on the left side. $12+7x=12+10x$ Subtract 7x from both sides. $12=12+3x$ Subtract 12 from both sides. $0=3x$ Divide both sides by 3. $x=0$
