Answer: y = 31
Step-by-step explanation: all you need to do is plug in the x
since x = -21 we can put: -21 + y = 10
now we add 21 to both sides giving us: y = 31
Answer:
(-21,22)
Step-by-step explanation:
x+y=10
x=-21
subtitue the x value
-21+y=2
solve for y
y=22
Then write your answer by ordered pair
