Question

if x+y=7and x-y=3 evaluate x^2+y^2​

Answer 1

Answer:

29 is your answer please give me some thanks please good morning

Answer 2

Answer:

29

Step-by-step explanation:

x - y = 7 so x = 3 + y

putting x = 3 + y in x + y = 7

3 + y + y = 7

3 + 2y = 7

2y = 7 - 3

2y = 4

y = 4/2

y = 2

now finding value of x by using y=2 in x+y=7

x + 2 = 7

x = 7 - 2

x = 5

putting x and y in x² + y²

5² + 2² = 25 + 4

=29
