Question

What is the solution to the system of equations?

Answer 1

So 
I will solve your system by substitution.x=−2;y=x+3Step: Solvex=−2for x:Step: Substitute−2forxiny=x+3:y=x+3y=−2+3y=1(Simplify both sides of the equation)Answer:x=−2 and y=1

Answer 2

Y = x + 3 ---------- (1)
x = -2      ---------- (2)

Sub (2) into (1) 

y = (-2) + 3
y  = 1

------------------------------
Answer: x = -2, y = 1
