Question 303363
{{{(2/3)X+5=10}}}first thing is to subtract 5 from both sides of = sign
{{{(2/3)X=5}}} with a fraction before X you would want to multiply by its reciprical to both sides
{{{cross((3/2)(2/3))X=5(3/2)}}}
{{{highlight(X=15/2)}}}


<p>
{{{(11/12 - 5/9)/(2/3)}}} find the Lowest Common Denominator for the 2 fractions in the numerator 9*4=36 and 12*3=36 so 36 is the LCD to change the fractions multiply by the common one to get 36 as the denominator
{{{(((11/12)(3/3))-((5/9)(4/4)))/(2/3)}}}multiply across numerator
{{{((33/36)-(20/36))/(2/3)}}}subtract the numerator fractions
{{{(13/36)/(2/3)}}}when dividing by a fracton it is the same as multiplying by the fractions reciprical
{{{(13/36)(3/2)}}}cross cancel what u can
{{{(13/12cross(36))(1cross(3)/2)}}}multiply accros
