Question 73390
{{{ 7(3x+11) = 9(3-6x) }}}
Start by distributing the 7 and the 9 across their respective quantities.
{{{ 21x + 77 = 27x - 54 }}}
since the 21x is the smaller x value, subtract it from both sides of the equation.
{{{ 77 = 6x - 54 }}}
Add 54 to both sides
{{{ 131 = 6x }}}
divide by 6
{{{ 131/6 = x }}}
Yes, it is okay to have a fraction.
