Answer:
The x-value is -1
The y-value is -1
Step-by-step explanation:
Given:
y = 4x + 3 ................{equatiion ( 1 )}
x + y = -2 ................{equatiion ( 2 )}
To Find:
x = ?
y = ?
Solution:
[tex]y = 4x + 3 ................{equation( 1 )}\\x + y =-2 ................{equation( 2 )}[/tex]
substituting y value in equation ( 2 ) we get
[tex]x+4x+3=-2\\5x=-2-3\\x=\frac{-5}{5}\\ x=-1[/tex]
substituting x value in equation ( 2 ) we get
[tex]-1+y=-2\\y=-2+1\\y=-1\\[/tex]
The x-value is -1
The y-value is -1
The Graph is attached with the solution A ( -1,-1)
