Question

4. Verify x-(-y) = x + y for the following values of x and y.
a) x = 113, y = 421
b) x = 223, y = 319
c) x = 835, y = 186
d) x = 643, y = 221​

Answer 1

Answer:

x-(-y) = x + y

a) x = 113, y = 421

----->

113-(-421)=113+421

113+421=113+421

534=534

LHS=RHS

b) x = 223, y = 319

----->

223-(-319)=223+319

223+319=223+319

542=542

LHS=RHS

c) x = 835, y = 186

----->

835-(-186)=835+186

835+186=835+186

1021=1021

LHS=RHS

d) x = 643, y = 221

----->

643-(-221)=643+221

643+221=643+221

864=864

LHS=RHS
