Question 162470
</pre><font size=4><b>
Given: {{{2-(3x-20)=4(x-2)}}}
{{{2-3x+20=4x-8}}}, distribute
{{{2+20+8=4x+3x}}}, combine similar terms
{{{30=7x}}}
{{{cross(30)4.2857/cross(7)=cross(7)x/cross(7)}}}, divide 7 to isolate x
{{{x=4.2857}}}
Check, go back to given:
{{{2-(3*4.2857-20)=4(4.2857-2)}}}
{{{2-(12.8571-20)=4(2.2857)}}}
{{{2-(-7.1429)=9.1428}}}
{{{2+7.1429=9.1428}}}
{{{9.1429>=9.1428}}}, close enough! we round it off the value of x.
Thank you,
