$x=2$

#### Work Step by Step

"Times" indicates multiplication. "Difference" indicates subtraction. "Quotient" indicates division.
$7(x-1)=70\div10$ $\longrightarrow$distributive property
$7x-7=70\div10$ $\longrightarrow$divide
$7x-7=7$ $\longrightarrow$addition property
$7x-7+7=7+7$ $\longrightarrow$simplify
$7x=14$ $\longrightarrow$multiplication property
$7x\div7=14\div7$ $\longrightarrow$simplify
$x=2$
