Question 915113
Replace every copy of y with 8. Then solve for x.


{{{2x + 4y = 50}}}


{{{2x + 4(8) = 50}}}


{{{2x + 32 = 50}}}


{{{2x = 50-32}}}


{{{2x = 18}}}


{{{x = 18/2}}}


{{{x = 9}}}


So when {{{y = 8}}}, the value of x is {{{x = 9}}}


Let me know if you need more help or if you need me to explain a step in more detail.
