Question 772399
{{{system(x=5y,3x-4y=11)}}}
Substitute {{{x=5y}}} into the second equation
{{{3*5y-4y=11}}}
{{{15y-4y=11}}}
{{{11y=11}}} divide by 11
{{{y=1}}}
substitute {{{y=1}}} into {{{x=5y}}}
{{{x=5*1=5}}}
{{{system(x=5, y=1)}}}
Check the answer
{{{system(5=5*1,3*5-4*1=11)}}}
{{{system(5=5,11=11)}}} - correct
Answer (5, 1)
