Question

If a+b=7
a-b=13

Find the value of a& b

Answer 1

A=10

B= -3

Explanation:

a+b=7 ---> 10+(-3)=7

a-b=13 ---> 10-(-3)=13

Answer 2

Answer: To solve for the values of a and b, we can use the method of elimination. Adding the two equations together eliminates b, giving us:

(a + b) + (a - b) = 7 + 13

2a = 20

a = 10

Substituting the value of a into one of the original equations, we can solve for b:

a + b = 7

10 + b = 7

b = -3

Therefore, the values of a and b are a = 10 and b = -3.
