Question 118618
Assume you mean:
{{{-(4x)/3}}} = {{{18/5}}}
:
Get rid of the denominator and the negative x, multiply both sides by -15
-15*{{{-(4x)/3}}} = -15*{{{18/5}}}
:
Cancel the denominators and change the signs
+5(4x) = -3(18)
:
20x = -54
:
x = {{{-54/20}}}
Reduces to:
x = {{{-27/10}}} or -2.7
:
:
Check solution in original equation
{{{-(4(-2.7))/3}}} = {{{18/5}}}
{{{(+10.8)/3}}} = {{{18/5}}}
Using a calc
3.6 = 3.6; confirms our solution of x = -2.7
