#x = 4#

Step 1) Expand the term within parenthesis:

#6x + 4(1 + 7x) = 140#

#6x + 4 + 28x = 140#

Step 2) Combine like terms on each side of the equation, in this case the left side only:

#34x + 4 = 140#

Step 3) Solve for #x# while keeping the equation balanced:

#34x + 4 - 4 = 140 - 4#

#34x = 136#

#(34x)/34 = 136/34#

#x = 4#
