Question 1

Y=x+2
y+1= – 4x
Is this ordered pair a solution of the system of equations? Help:(

Question 2

Put value of y in Equation 1 in Equation 2.

$\looparrowright \sf y + 1 = - 4x$

$\\ \\$

$\looparrowright \sf (x + 2) + 1 = - 4x$

$\\ \\$

$\looparrowright \sf x + 2 + 1 = - 4x$

$\\ \\$

$\looparrowright \sf x +3= - 4x$

$\\ \\$

$\looparrowright \sf x + 4x= - 3$

$\\ \\$

$\looparrowright \sf 5x= - 3$

$\\ \\$

$\looparrowright \sf x= ( - 3)/(5)$

$\\ \\$

Let's find value of y :

$\\ \\$

$\looparrowright \sf y=x+2$

$\\ \\$

$\looparrowright \sf y= ( - 3)/(5) +2$

$\\ \\$

$\looparrowright \sf y= ( - 3 + 10)/(5)$

$\\ \\$

$\looparrowright \sf y= (7)/(5)$

Solution:

$\looparrowright \sf \bigg( ( - 3)/(5) , (7)/(5) \bigg)$
