Question

( solve for y. then find the value of y for each value of x)
4y=5x-8; -2,-1,0

Answer 1

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 ,

`\sf\longrightarrow` 4y = 5x -8

`\sf\longrightarrow` y = 5x-8/4

At x = -2 ,

`\sf\longrightarrow` y = 5(-2) -8/4

`\sf\longrightarrow` y = -10-8/4

`\sf\longrightarrow` y = -18/4

`\sf\longrightarrow` y = -9/2

At x = -1 ,

`\sf\longrightarrow` y = 5x -8/4

`\sf\longrightarrow` y = 5(-1) -8/4

`\sf\longrightarrow` y = -5-8/4

`\sf\longrightarrow` y = -13/4
