Question 306312
Given: {{{2X/5 + 1/3 = 7X - 2/15}}}
15 is the lcd.  Convert the other fractions to have a denominator of 15
{{{3*(2X)/15 + 5/15 = 7X - 2/15}}} Multiply everything by 15
{{{6X + 5 = 105X - 2}}} Subtract 6X from both sides
{{{5 = 99X - 2}}} Add 2 to both sides
{{{7 = 99X}}} Divide both sides by 99
{{{highlight(7/99 = X)}}}
or {{{highlight_green(0.0707 = X)}}}
