Given :-

  • 4y = 5x - 8

To Find :-

  • To solve for x and find the value of y at the given values of x .

Solution :-

The given equation to us is ,

[tex]\sf\longrightarrow[/tex] 4y = 5x -8

[tex]\sf\longrightarrow[/tex] y = 5x-8/4

At x = -2 ,

[tex]\sf\longrightarrow[/tex] y = 5(-2) -8/4

[tex]\sf\longrightarrow[/tex] y = -10-8/4

[tex]\sf\longrightarrow[/tex] y = -18/4

[tex]\sf\longrightarrow[/tex] y = -9/2

At x = -1 ,

[tex]\sf\longrightarrow[/tex] y = 5x -8/4

[tex]\sf\longrightarrow[/tex] y = 5(-1) -8/4

[tex]\sf\longrightarrow[/tex] y = -5-8/4

[tex]\sf\longrightarrow[/tex] y = -13/4
