Question 465170


{{{4x+y+1/2 =14}}}

to check this using substitution method, you need {{{x}}} and {{{y}}} values ...plug them in your equation and if the left side of equation is equal to the right side  {{{x}}} and {{{y}}} values are solutions.

I will take for  {{{x=2}}} and {{{y=5}}} and check if these values are solutions:


using substitution method we have {{{4*2+5+1/2 =14}}}

{{{8+5+1/2 =14}}}

{{{13(1/2) =14}}}

{{{13.5 =14}}}.......... the left side of equation is NOT equal to the right side  {{{x}}} and {{{y}}} values are NOT solutions.


now, I will take for  {{{x=2}}} and {{{y=5.5}}} and check if these values are solutions:


using substitution method we have {{{4*2+5.5+1/2 =14}}}

{{{8+5.5+1/2 =14}}}

{{{13.5 +0.5 =14}}}

{{{14 =14}}}.......... the left side of equation IS equal to the right side  {{{x}}} and {{{y}}} values ARE solutions.
