Answer
$5(x+2)=8x-11$
$x=7$
Work Step by Step
"Times indicates multiplication, "Sum" indicates addition. The term preceding "less than" is the subtrahend".
$5(x+2)=8x-11$ $\longrightarrow$distributive property
$5x+10=8x-11$ $\longrightarrow$addition property
$5x+10-5x+11=8x-11-5x+11$ $\longrightarrow$simplify
$21=3x$ $\longrightarrow$multiplication property
$21\div3=3x\div3$ $\longrightarrow$simplify
$7=x$
