See below

#x=-300#

To solve #x/10+50=20#,

subtract 50 from both sides

#x/10+50-50=20-50#

#x/10=-30#

multiply both sides by 10

#10*x/10=-30*10#

#x=-300#

#x=-300#

Refer to the explanation for the process.

Solve:

#x/10+50=20#

Multiply both sides by #10#.

#10xx x/10+50xx10=20xx10#

Cancel the #10# in #x/10# on the left-hand side.

#color(red)cancel(color(black)(10))xx x/color(red)cancel(color(black)(10))+50xx10=20xx10#

Simplify.

#x+500=200#

Subtract #500# from both sides.

#x+500-500=200-500#

Cancel #500# on the left-hand side.

#x+color(red)cancel(color(black)(500))-color(red)cancel(color(black)(500))=200-500#

Simplify.

#x=-300#
