Question 46139
Let the two numbers be x and (x+1). Write the equation from the problem.

{{{2x+7(x+1) = 88}}} Simplify and solve for x.
{{{2x+7x+7 = 88}}}
{{{9x+7 = 88}}} Subtract 7 from both sides.
{{{9x = 81}}} Divide both sides by 9.
{{{x = 9}}} and {{{x+1 = 10}}}

Check:

2(9) + 7(10) = 18 + 70 = 88 It checks!
