Question

Identify the solution

Answer 1

The x-value is -1

The y-value is -1

Explanation:

Given:

y = 4x + 3 ................{equatiion ( 1 )}

x + y = -2 ................{equatiion ( 2 )}

To Find:

x = ?

y = ?

Solution:

`y = 4x + 3 ................{equation( 1 )}\\x + y =-2 ................{equation( 2 )}`

substituting y value in equation ( 2 ) we get

`x+4x+3=-2\\5x=-2-3\\x=(-5)/(5)\\ x=-1`

substituting x value in equation ( 2 ) we get

`-1+y=-2\\y=-2+1\\y=-1\\`

The x-value is -1

The y-value is -1
