Sagot :
x + y = 144
x - y = 22
2x = 166
x = 83
83 + y = 144
y = 144 - 83
y = 61
x - y = 22
2x = 166
x = 83
83 + y = 144
y = 144 - 83
y = 61
Answer:
The two numbers are 157 and 13
Step-by-step explanation:
Let x and y be the two numbers
x+y = 170
x-y =144
Add the two equations together
x+y = 170
x-y =144
-------------------
2x= 314
Divide by 2
2x/2 = 314/2
x =157
Now find y
x+y = 170
157+y = 170
y = 170-157
y =13
