[tex] \dashrightarrow \sf - 10 x + 3y = 5[/tex]
Put value of x I.e y - 4 in the equation
[tex] \\ \\ [/tex]
[tex] \dashrightarrow \sf - 10(y - 4) + 3y = 5[/tex]
[tex] \\ \\ [/tex]
[tex] \dashrightarrow \sf - 10y + 40 + 3y = 5[/tex]
[tex] \\ \\ [/tex]
[tex] \dashrightarrow \sf - 10y+ 3y + 40 = 5[/tex]
[tex] \\ \\ [/tex]
[tex] \dashrightarrow \sf -7y + 40 = 5[/tex]
[tex] \\ \\ [/tex]
[tex] \dashrightarrow \sf -7y = 5 - 40[/tex]
[tex] \\ \\ [/tex]
[tex] \dashrightarrow \sf -7y = - 35[/tex]
[tex] \\ \\ [/tex]
[tex] \dashrightarrow \sf \cancel-7y = \cancel - 35[/tex]
[tex] \\ \\ [/tex]
[tex] \dashrightarrow \sf 7y = 35[/tex]
[tex] \\ \\ [/tex]
[tex] \dashrightarrow \sf y = \dfrac{35}{7} [/tex]
[tex] \\ \\ [/tex]
[tex] \dashrightarrow \boxed{\sf y = 5} \star[/tex]
[tex] \\ \\ [/tex]
Now Let's find value of x.
[tex] \\ \\ [/tex]
Put value of y I equation: x = y -4
[tex] \\ \\ [/tex]
[tex] \dashrightarrow \sf x = y - 4[/tex]
[tex] \\ \\ [/tex]
[tex] \dashrightarrow \sf x = 5 - 4[/tex]
[tex] \\ \\ [/tex]
[tex] \dashrightarrow \boxed{\sf \: x = 1} \star[/tex]
[tex] \\ \\ [/tex]
.°. value of x and y = 1 and 5 respectively
