У= - 3х - 3
у = х + 5

(x,y)=(-2,3)

Step-by-step explanation:

Since both expressions -3x-3 and x+5 are equal to y, set them equal to eachother forming an equation in x

-3x-3=x+5

solve the equation for x

x= -2

substitute the given value of x into the equation y=x+5

y= -2 +5

solve the equation for y

y=3

the possible solution  of the system is the ordered pair (x,y)

(x,y) = (-2,3

check if the given ordered pair is the solution of the system of equations

{3= -3x(-2) -3

{3= -2 +5

simplify the equalitites

{3=3

{3=3

since all the equalitites are true, the ordered pair is the solution of the system

(x,y)=(-2,3)
