Question

Solve for X and Y graphically
X+Y=7
X-Y=3

Answer 1

★ Answer :

x + y = 7 ......(1)

x - y = 3 ......(2)

From equation (1).

→ x = 7 - y

Put value of x in equation (2).

→ (7 - y) -y = 3

→ 7 - 2y = 3

→ -2y = -4

→ y = -4/-2

→ y = 2

Now, Put value of y in equation (1).

→ x + 2 = 7

→ x = 7 - 2

→ x = 5
