I will solve your system by substitution.y=x−2;y=−x−4Step: Solve y=x−2for y:Step: Substitute x−2foryiny=−x−4:y=−x−4x−2=−x−4x−2+x=−x−4+x (Add x to both sides)2x−2=−42x−2+2=−4+2 (Add 2 to both sides)2x=−22x2=−22(Divide both sides by 2)x=−1Step: Substitute−1 for x in y=x−2:y=x−2y=−1−2y=−3 (Simplify both sides of the equation)Answer:x=−1 and y=−3








x= -1
y = -3
